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?
a.2x – y = –4
b.10x – 5y = –20
c.7x = 39
d.13x = 39
