Problem:
Solve for y:
-2x%2B4y=8x%2B12
2x-2x%2B4y=2x%2B8x%2B12
%282-2%29x%2B4y=%282%2B8%29x%2B12
0x%2B4y=10x%2B12
4y=10x%2B12
4y%2F4=%2810%2F4%29x%2B12%2F4
y=%285%2F2%29x%2B3
Happy Calculating!!!

Problem:
Solve for y:
-2x + 4y = 8x + 12
:
Add 2x to both sides and you have:
4y = 8x + 2x + 12
4y = 10x + 12
:
Divide both sides by 4:
y = (10/4)x + 12/4
y = 2.5x + 3
