-4y = 3 - 2x
add 2x to both sides
2x - 4y = 3 is your answer
OpenStudy (aripotta):
i'm wondering how you got your answer tho?
OpenStudy (anonymous):
I think i did it backwards or something, i added 2x to both sides, got -2 and 4, probably just put it in wrong i guess.

7 - 3(x - y) = -5x + 2
first distribute the -3
7 - 3x + 3y = -5x + 2
subtract 7 from both sides
-3x + 3y = -5x - 5
add 5x to both sides
2x + 3y = -5

Ohhh.. Otay, so it's A. That makes sense, somewhat.
OpenStudy (aripotta):
no, it's c
OpenStudy (anonymous):
Oh.. I though A bc adding 5 n 2 >.> But thank you.

this is your answer 2x + 3y = -5. i just worked it out a few minutes ago. and c matches our answer
OpenStudy (aripotta):

OpenStudy (anonymous):
Add 5x to both sides, n that equals that answer. Lmfao, leave it up to me.
