Use the substitution method to solve the system of equations. choose the correct ordered pair. 2y + 2x = 8 2y - 4x = 2

2y + 2x = 8
2y - 4x = 2

2y = 8 - 2x (divide by 2 on both sides)
y = 4 - x (insert this into the second equation

2*(4-x) - 4x = 2
8 - 2x - 4x = 2
8 - 6x = 2
-6x = 2 - 8
-6x = -6
x = 1 (insert this into either of the first two equations)

2y + 2*1 = 8
2y + 2 = 8
2y = 8 - 2
2y = 6
y = 6/2
y = 3

(x,y) = (1,3)
