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
