    Answer: A) Multiply both sides of the top equation by 2.

    Step-by-step explanation: The x-coefficient of the first equation (the number that is next to the x) is 4, and the x-coefficient of the second equation is 8, in order to them to be equal, we need to multiply the first equation by 2 (both sides), so the correct answer is the corresponding to option A, the equations would be:

    8x+4y=8 first equation (after multiply it by 2)

    8x-y=18 second equation

    The answer is A. Multiply both sides of the top equation by 2

    So since we know that 4 * 2 = 8, it would only make sense to multiply both sides by 2 so that the top equation has the x coefficient be 8.
