Solve this system of linear equations. x = -20 - 2y
9x = -60 + 2y

A)8,-6
B)-8,6
C)-8,-6
D)8,6

(-8,-6)

Step-by-step explanation:

You add the equations together, the 2y and -2y cancel out. You isolate x, then plug the answer you get for x from that into one of the equations. The amount you get for y is the y-coordinate and the amount you had for x is the x-coordinate. To check, try putting the y value into the equation you didn't plug the x into before. If you get the same x value as you had before, it means it's correct, I think.
