Answer 1

Answer:

x  = - 1,  y = 4

Step-by-step explanation:

A. We are going to use elimination method because we have +2y and -2y, and when we add these equations +2y and -2y are going to be eliminated.

B.

  x + 2y = 7

+ 3x - 2y  = -11

 4x         = - 4

  x         = - 1

x + 2y = 7

-1 + 2y = 7

     2y = 8

       y = 4
