4x-2y=4 (-4x+4y=8)

OpenStudy (solomonzelman):

you meant to say that you need to solve a system of equations - 4x-2y=4 and -4x+4y=8 right ?

OpenStudy (anonymous):

Thats correct

OpenStudy (solomonzelman):

4x -2y =4 + -4x +4y =8 -------------------------- 0x + 2y = 12 So, 2y=12 that means, y=6. plug in y to solve for x. 4x-2y=4 4x-2(6)=4 4x-12=4 4x-12 +12 = 4 + 12 4x=16 x=? (you tell me)
