The system of equations can be solved using linear combination to eliminate one of the variables.

2x - y = - 4 → 10x - 5y = - 20

3x + 5y = 59 → 3x + 5y = 59

13x = 39

Which equation can replace 3x + 5y = 59 in the original system and still produce the same solution?

2x - y = - 4

10x - 5y = - 20

7x = 39

13x = 39
