2 over 6

You stupid fucking nigger it's 6 over 17 go die

use simple logic. theres almost no need for actual math

Is OP actually retarded?

Jesus man this looked so easy at a glance but now that I'm really looking at it I can't remember what the fuck to do either.

Nice dubs though. Show those to your stats teacher and he should give you a pass on this one.

fuck! it switched to a new one
you were at least right user
The problem isn't the math it's I don't remember the process for solving it

The way you solve this is you pick your favorite, and fill it in x. Then see if the equation is correct. If it isn't, pick a different number

3(x-2)/7 = -2 | * 7
3(x-2) = -2*7 | / 3
x - 2 = -2*7/3| + 2
x = 2-2*7/3 = 6/3-14/3 = -8/3

that works for simple equations this one is a decimal/fraction

Then just pick your two favorite numbers and use the one over the other as your guess

It's 6/17

WOLFRAM ALPHA, NIGGA

move fucking things around

proof here m.wolframalpha.com/input/?i=3(x-2)/7=-2&x=8&y=7

>*7
3(x-2)=-14x
3x-6=-14x
>+14x
>+6
17x=6
>/17
x=6/17

What the fuck you fucking retard that's not the equation OP gave can't you even fucking read god you're such a worthless piece of shit

-2x not -2

multiply both sides by 7 so you have

3(x-2)=-14x

mutiply the 3 to whats in the parenthesis
3x-6=-14x
add 14x to both sides
17x-6=0
add 6 to both sides
17x=6
divide by 17
x=6/17

god damnit, forgot about the x on the right side.

3(x-2)/7=-2x | *7
3x-6=-14x | +14x
17x-6=0 |+6
17x=6|:17
x=6/17

except after three wrong answers it confirmed
6/17

Last one

Got the same:

do you not know how to cross multiply you tard?

1. multply both sides by 8 and distribute the 5 to the parenthesis stuff

5x-20=-16x

2. add 16x to both sides
21x-20=0

3.add 20 to both sides
21x=20

4.divide both sides by 21
x=20/21

are you in highschool or something? This really isn't that hard, its just basic algebra

So by the end always divide the number with the variable?
Like I said it's been 6 years since I did any algebra it's why I took statistics. Just forgot this stuff is all.
when the fuck did this site exist

So if you have something like 5x then yea you need to divide that by 5 because you dont care what 5x is equal to, you want to know what x is equal to

> when the fuck did this site exist
Jesus nigger you weren't kidding were you, what have you been doing the past years?

>picked statistics
>knows shit about algebra

Get ready to fail

jacking off and playing video games, was homeless for a bit too.
alright thanks
Nah they actually teach the equations I need in class so you know learning actually happens. I've got an at the midterm so even if i bomb everything else I'll still pass

>americunts taking statistic classes
>cant solve math problem for 10 year olds
Go take art classes or something... you'll have to learn a lot more math if you want to learn about statistics.

an A*

Hey you can't fault a man for trying but this does seem a bit ridiculous
