Answer 2

Answer:

Step-by-step explanation:

1) Name the 2 equations:

    41x + 53y = 135 ......(1)

    53x + 41y = 147 ......(2)

2) Make x the sublect of the formula in (1)

   41x = 135 - 53y

   x = (135 - 53y)/41 .....(3)

3) Substitute for x  in (2)

   53((135 - 53y)/41) + 41y = 147

  7155 - 2809y + 1681 = 6027

  therefore, y = 1

4) Substitute for y in (1)

   41x + 53(1) = 135

  41x + 53 = 135

  therefore, x = 2 and y = 1
