Change the equation 3x + 2y = -16 into: -3x -2y = 16
2x - 5y = 2
+ -3x - 2y = 16
-x - 7y = 18
-x = 18 + 7y
x = -7y - 18
Plug "x" into either one of the equations
3(-7y-18) + 2y = -16
-21y - 54 + 2y = -16
-19y - 54 = -16
-19y = 38
y = -2
Since we have the actual value of y, we can plug that into either one of the equations to find the value of x.
3x + 2(-2) = -16
3x - 4 = -16
3x = -12
x = -4
So.. The answer for the problem is D (-4, -2).
