Answer 2

Answer:

  (a) x + y = 15                    x - y = 3

  (b) x + y = 0                      x - y = 2

  (c) 2x - y = 3                   4x + y = 3

  (d) 2x - 9y = 9               5x + 2y = 27

  (e) x + 4y = -4               3y - 5x = -1

  (f) 2x - 3y = 2                  x + 2y = 8

  (g) x + y = 7                  2x - 3y = 9

  (h) 11y + 15x = -23        7y - 2x = 20

   (i) 5x - 6y = 2                6x - 5y = 9
