Solve the system of equations by the addition method
3x+2y= -7
2x-2y+2

Answer 1

Answer:

x = -1

Step-by-step explanation:

3x + 2y = -7

2x - 2y = 2

First, we need to find a way to cancel out one of the variables. This problem makes it easy because the +2y and -2y will cancel out already. We then add the equations together.

  3x + 2y = -7

+ 2x - 2y = 2

-------------------------

 5x = -5

Now, we simply divide both sides by 5 to isolate the x.

5x/5 = -5/5

x = -1

This leaves us with x = -1.

Hope this helps!
