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
