Question: The system of equations can be solved using linear combination to eliminate one of the variables. 2x - y= -4 - 10x - 5y =

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? O 2x - y = -4 O 10x - 5y = -20 O 7x = 39 13x = 39
