Answer:

x = 3 and y = 7

Step-by-step explanation:

  2x + y = 13

+    x - y = -4      (adding both equations)

 3x - 0y = 9

        3x = 9

          x = 9/3

          x = 3

now substituting

x - y = -4

3 - y = -4

  - y = -4 - 3

  - y = -7

    y = 7     (the negative sign on both sides get canceled)

Therefore,

x = 3 and y = 7
