Well, Sup Forums? Can you figure it out?

Well, Sup Forums? Can you figure it out?

Well, I'm getting that -7 is congruent to 19, so 0 is congruent to 26.

I guess it's happening in Z25.

SO NO

X^2 = 26. that's about as far as I am willing to get.

The answer is: 'no'.

>X^2
What the fuck are you doing?

Yes, you wrote the question wrong.

x = -6
(-6) - 7 = 19 + (-6)

...

x-7=19+x
(x-7)^2=(19+x)^2
x^2-14x+49=x^2+38x+361
-14x+49=38x+361
24x=312
x=13

Check:
13-7=19+13
6=32 (???)

I tried.

Almost. But no.

elaborate

(-6) - 7 = -13
19 + (-6) = 13

-13 is not 13

sorry your right just used a calculator was doing it in my head

this problem is impossible to solve

you can't take one number and add it, while subtracting it and get an answer

As pointed out earlier, 0=26 is not a strange result if the operation is occurring in a cyclic group.

Try to keep up.

Woah.

No Solution, that's the answer.

>having to use a calculator for simple substraction/addition

4 in Z/26Z

x + 26 = x
Obviously that's not true.
So the answer is none.

I'd like to remind you all that this is a Christian board; we'd all appreciate it if you practiced your witchcraft elsewhere. Thank you.

Though the modular integer example is correct, the generalization is not. The integers as a whole form a cyclic group under addition (generators 1, -1). Baka baka!

Are you smarter than Yui?
You are if you can solve 4.(3)

...

That's not even a solveable equation

X to the power of 2

Wtf are you doing?

Math

0=26

Please write your working for this retard, cause i still have no idea how you got it

x - 7 = 19 + x | +7
x = 26 + x | +x
x^2 = 26

farthest i got is (x+y)(x+4)+3

wtf you doing. You do realize that its all addition and subtraction, so having a power in here is almost impossible, right?

that's not how it works holy shit

Sorry that I'm not a turbonerd sperg like you. Try doing a better job then.

In what sense do you mean "solve"? It's a function.

x(x+y+4) + y(-2y+5) + 3

not that user.

x - 7 = 19 + x
-x + x - 7 = 19 + x - x
-7 = 19

if I'm not wrong these numbers are from an alternative universe.

This is why you brows Sup Forums Sup Forums at night. You failed in life.

See

>-7=19
The answer is find a new teacher.

Jesus christ user, wtf is wrong with you? That's not how you do math at all.

that's fucking algebra basics you ignorant

stop trying, it's bait. not solveable.
also, I strongly urge you to retake algebra 101

Yea? Well your browsing Sup Forums right now, I doubt you know much of anything.

It always makes me smile when I see people fall for this.

but let me change it for you peasant

x - 7 = 19 + x
-x + x - 7 = 19 + x - x
-7 = 19
-19 - 7 = 19 - 19
-26 = 0

-26=0 or 0=26

You are fucking retarded.

There's no solution you god damn moron. When you're setting two functions equal to each other like that, you're finding the point (or set of points) which satisfy both equations.

Since the line x - 7 never crosses the line x + 19, there is no solution.

Correct.

wtf dude. I know it's not right. Read the goddamn post
