The value of x is equal to -2.
The value of y is equal to 0.
y = -2x - 4
y = x + 2
Because we have two values of y, we can set them equal to each-other.
-2x - 4 = x + 2
Add 2x to both sides.
-4 = 3x + 2
Subtract 2 from both sides.
-6 = 3x
Divide both sides by 3.
-2 = x
Because we have a value for x, we can plug it into either equation to solve for y.
y = -2(-2) - 4
y = 4 - 4
y = 0
