4x + 2y = 4
6x - 8 = - 2y
Both equations are divisible by 2, so divide both sides of both equations by 2.
2x + y = 2
3x - 4 = - y
Since the second equation has - y on one side, we can multiply both sides by - 1 to solve for y.
y = - 3x + 4
Now we substitute y of the first equation with - 3x + 4.
This is the substitution method.
2x + y = 2
2x - 3x + 4 = 2
-x + 4 = 2
-x = - 2
x = 2
Now we substitute 2 for x in the first original equation and solve for y.
4x + 2y = 4
4 (2) + 2y = 4
8 + 2y = 4
2y = - 4
y = - 2
The solution is x = 2 and y = - 2
