Question

3x + 2y = 7 y = x – 4 (3, –1) (2, 6) (6, 2) (–1, 3)

Answer 1

3x + 2y = 7

y = x - 4

3x + 2(x - 4) = 7
3x + 2x - 8 = 7
               5x = 7 + 8
               5x = 15
                 x = 15/5
                 x = 3

y = x - 4
y = (3) - 4
y = -1


the solution to the set is (3, -1)

hope this helps :)
