You can put this solution on YOUR website! Solve the system of equations using the elimination method. Enter the answer as an ordered pair.
x - 2y = 12
4x + 2y = 8
-------
Add and solve for "x":
5x = 20
x = 4
-----
Solve for "y":
x - 2y = 12
4 - 12 = 2y
y = -4
------------------
Ans: (4,-4)

You can put this solution on YOUR website! x - 2y = 12
4x + 2y = 8
------------
5x = 20 {added the two equations}
x = 4 {divided each side by 5}
x - 2y = 12 {top equations}
4 - 2y = 12 {substituted 4, in for x, into top equation}
-2y = 8 {subtracted 4 from each side}
y = -4 {divided each side by -2}
