Problem: How to solve using the elimination method
-6x-6y=-12
-6x+7y=14

1) -6x - 6y = -12
2) -6x + 7y = 14

Subtract equation 1 from equation 2.

  -6x + 7y =  14
-(-6x - 6y = -12)
-------------------
        13y =   26
13y = 26
13y/13 = 26/13
y = 2

Solve for x.

-6x - 6y = -12
-6x - 6(2) = -12
-6x - 12 = -12
-6x - 12 + 12 = -12 + 12
-6x = 0
x = 0

Answer: x = 0, y = 2
