Solve the system using elimination. 5x = –25 + 5y 10y = 42 + 2x

5x = –25 + 5y rewrite 5x - 5y = -25
10y = 42 + 2x rewrite 2x - 10y = -42

multiply 1st equation by 2
10x - 10y = -50
2x - 10y = -42
subtract to eliminate y and solve for x
8x = - 8
  x = -1

2x - 10y = -42
2(-1) - 10y = -42
-2 - 10y = -42
-10y = -40
     y = 10

answer
solution (-1, 10)
