5x+7y=12 Original Problem
5(36-7y)+7y=12 Substitute x for 36-7y
180-35y+7y=12 Distributive Property
180-28y=12 Combine Like Terms
-28y=-168 Subtract 180 from both sides
y=6 Isolate variable y by dividing
-28 from both sides.

5x+7y=12
x=36-7y

5(36-7y) + 7y = 12

180 - 35y + 7y = 12

168 = 35y - 7y

168 = 28y

168/28 = y

6 = y

Substitute 6 for y in the first equation.
