Question

Solve -x + 4y - 28 = 0 for y.

Answer 1

y=x/4+7

Explanation:

-x+4y-28=0 add -x to both sides

4y-28=x+0 add -28 to both sides

4y=x+28 divide both sides by 4

y=x/4+7

Answer 2

y = x/4 +7

Explanation:

-x + 4y - 28 = 0

Add x to each side

-x +x+ 4y - 28 = 0 +x

4y -28 =x

Add 28 to each side

4y - 28+28 = x+28

4y = x+28

Divide each side by 4

4y/4 = x/4 +28/4

y = x/4 +7
