Six math equasions 95% of people can't solve

Six math equasions 95% of people can't solve.

(1.) x + x = x - x
(2.) (x)x = x(x)
(3.) I'm thinking of a number between minus twelve and minus 7, what is it?
(4.) 3(x-3)+4=x
(5.) (x/x)x = -x
(6.) x-x+x-x+x-x+x=x+x-x+x-x+(-x)

-11
pi
???

>21

2x=0

0/0 = ?

Is axiom or order of operation
-19

-14.5

(X/x)x+x=0
Where x is any value.
Nothing to solve.

>1 + 1 = 1 - 1
I'm not even going to bother marking the rest of your answers

X=0

Plug that for any x and solved.

0=0

he's right, tho

0
1
-9
2.5
-1
0

these are all wrong

this poster got furthest:

1. x = 0
2. x = anything
3. x = -12

idk the rest

Explain

fuck you I hate math

2x+5=0
X=2.5

>1 + 1 = 1 - 1
who said x has to be the same all the time?

This is not math and bet op can't solve second orders.

uhhh, 6th grade math?

0
Any pair of commutative functions
faggot
5/2
no real-function answer exists
0

>quick think of the most complex maths term i know

people ITT seem to think that x is different for every equation. what makes you think that it can't be different within the same equation?

these are all wrong

If this is correct
why?

>these are all wrong
No they aren't, faggot. Although really, the second one is me being intentionally obtuse.

it adds up

Then fucking write it facebook. Jfc.

Uuuugh show how and why.

If x is not a variable then define x.

>5/2
lol, try again
>no real-function answer exists
big words from a small mind

1+1=w!aaaaaaaaaaaaaaaaaaaa(y)more squared

>x + x = x - x
>x=1

Proof:
1+1=1-1

it's balanced: 2 ones on the left, 2 ones on the right, + meaning: "left side", - meaning "right side", = meaning "balance"

because variables are defined for the expression they are in. ie, all x’s in an equation must have the same value. this is just standard convention. if you want another value for the variable just use a different variable like n, y, z, etc

Ok, I can see that. What about one with an answer pi?

Ah, it makes sense, thanks.

...

>3(x-3)+4=x
>x = pi

3.14159265359(3.14159265359-3)+4=3.14159265359
put it into your calculator -> it works

Oh god.. They have to be, otherwise it would be x y z or a b c.

Even then it's still wrong since it has to be the same value on both sides of the equasion. Please go back to school

wtf kind of psuedo math are you trying to push here

>they HAVE to be, because x can't be 1 and -1 at the same time
>because you can't be male and a female at the same time
>oh wait
>you actually can be
Try again, sweety.

Holy incest

...

...

I like it :/

ARE THESE MATH EQUATIONS OR LOGIC EQUATIONS YOU FUCKING COCK

get assfucked by a nail-driver

Don't put in wiggly shit ass characters, you fucking asshole greek. Put in 3.14159265359 exactly.

holy hell cant tell if bait or actually brain dead

Pi had more digits than that

>1+1=1-1
>2=0
>i failed first grade

Suuure hes right

holy shit, it actually works

How are those wrong?

The greek pi, maybe, but US is not metric, you idiot.

>x+x=x-x
2x=0
x=0

>(x)x=x(x)
x2=x2
x can be any real number

>I'm thinking of a number between minus twelve and minus 7, what is it?
-12(x/x)x=-x
2x=0
x=0

>x-x+x-x+x-x+x=x+x-x+x-x+(-x)
x=0


Now fuck off faggots

First number is 3

Everybody seriously arguing in here needs to get shot.

Obviously fucking troll

1) x=0
2) x=1
3) -12

There's so little difference between 3.14159265359 and 3 it doesn't make a measurable difference.

...

Clearly not USA

>greek pi
now look up the US pie

You got 2, 3, 4, and 5 wrong

Zero b isn't a solution to x/x*x=-x. You get 0/0 which doesn't have a real value

> pie
> pi

Only one I got wrong was 2, x*x=x*x for all numbers

It's the same thing. Pi is Greek, metric, and US standard

π

>0/0 which doesn't have a real value
Ech. 0/0 is the most balanced equation there is. You don't even need the scales or balancer-signs (=) because on each side you get the most smallest element (0) thus you don't even need it.

0
1
2.5
-1
annoying

>US can be metric and not metric at the same time
consult with this genius

The simplest answer is that you're pulling all of this out of your ass to prove a point about those stupid fruit/shape "equations"

1. x+x = x-x, x=0
2. (x)x=x(x), axiom of multiplication. Works for all numbers
3. -12

(x/x)x=-x
Start off by doing paranthesis
x/x = 1
1*x
1*x=-x
Move over x from right side to left side
x+x=0
2x=0
x=0

And you said there were no solutions

Is pi a measurement for distance, weight, exc?

You intentionally try to reduce x to zero. You can't fool everyone with that shit trick, you know?

x E (-inf ; inf)
0
not a math equation
x = 5/2
x E (-inf ; inf)

Oh shit I'm actually retarded

Simple really. Should've seen it before. Thanks.

I thought this was high school homework :)

>I decide what is math and what isn't
sure, babby

Feels like it. I'm so high I have to check my work by showing it.

>(1.) x + x = x - x
x=-x
x=0
>(2.) (x)x = x(x)
true for all x in R, C
>(3.) I'm thinking of a number between minus twelve and minus 7, what is it?
-12(5.) (x/x)x = -x
x=-x
x=0
>(6.) x-x+x-x+x-x+x=x+x-x+x-x+(-x)
x=0

>2=0
Typical

Still the closest one to the right answers. I wish we could solve 5 and 6 as well. I've never seen so advanced math in my life.

>itt posters rage
>not knowing this is how our education system is

Two can be equal to zero if you give it time. Everything withers away in nature. Just because you write down two and look at it for like 2 seconds it doesn't mean you looked at long enough for it to start to decompose.

Nice job m8

Shit, typoed #6. x-x+x-x+x-x+x=x+x-x+x-x+(-x), x=0.

What else do you show ;o

The "math" they taught us at school was ridiculous. Eleven comes after ten, like, wtf lol. There's obviously a hole between the two. It's ten-hole-eleven-hole-twelve. Thank god my father is a physics major, he made the whole thing more clear for me.

I know, there are differences between US and metric for e, pi, and mol.

True.

Ive ignored hole my whole life.

He's right, equation means equality (which can be solved or not), and that's not the case

>(1.) x + x = x - x
1
>(2.) (x)x = x(x)
0
>(3.) I'm thinking of a number between minus twelve and minus 7, what is it?
-10
>(4.) 3(x-3)+4=x
π
(this one blew my mind)

>(5.) (x/x)x = -x
only 0 can be the answer
>(6.) x-x+x-x+x-x+x=x+x-x+x-x+(-x)
Tricky one. 0.5

>only 0 can be the answer
>(x/x)x = -x
(0/0)0 = -0
+0 = -0
Of course! How didn't I think of this?

I just can't understand why the fucking world don't adapt the US system already.

(1.) 0
(2.) this could literally be any number. 5x5 = 25. 5x5 = 25
(3.) It's NEGATIVE. Not "minus" you fucking idiot. -11 -10 -9 -8 any of these are correct.
(4.) -2.5
(5.) Nonsense, all of a variable are either positive or negative. nothing preceding -x could possibly end up as -x if they're all positive as is stated.
(6.) 0

I love the american way in the sciences.

"Greek metric pi goes on for 7 trillion characters?"
"FUCK THAT! Nobody has time for that shit, we need to calculate already using pi. From now on pi = 3.13159265359"

Greeks be like:
>you can't do that!
US be like
>I just did and it works even better than your infinite pie, so what are you going to do about it?

>(5.) (x/x)x = -x
only 0 can be the answer

God damn it you're right.

>(5.) Nonsense, all of a variable are either positive or negative. nothing preceding -x could possibly end up as -x if they're all positive as is stated.
lol, do you even basic math? We already solved it without you:

0
anything
-10
2.5
no solution (the possible solution 0 is not in the domain)
0

>lol, do you even basic math? We already solved it without you

That was also a post only done 5 minutes before mine. I wasn't around for that correct answer fag. "we" as in "some other guy I'm taking credit from" kek. 10/10 faggotry.

The US system is the old ways.
