Question 495607

  2x + y = -6 ----- equation 1
  3x + y = -10 ----equation 2

first of all subtract equation 1 from equation 2

  (2x - 3x)+ (y -y) = (-6 - -10)

     -x + 0 = 4

      -x = 4

      x = -4

 substitute x = -4 into equation 1

     2x + y = -6

     2(-4)+ y = -6

     -8 + y = -6

      y = -6 + 8

      y = 2


    { x = -4 , y = 2 }
