he 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
