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

y = x/4 + 7

Step-by-step 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

y=x/4+7

Step-by-step 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
