3x+2y=-4
x+2y=-8
Subtract the second equation from the first.
3x + 2y = -4
-(x + 2y = -8)
----------------
2x = 4
x = 2
Substitute the value of x into the second equation.
x + 2y = -8
2 + 2y = -8
2y = -10
y = -5
To check, substitute the values for x and y into the first equation.
3x + 2y = -4
3(2) + 2(-5) = -4
6 - 10 = -4
-4 = -4
They check. x = 2, y = -5
