Given the system of equations presented here:

4x + y = 4

2x + 7y = 28

Which of the following actions creates an equivalent system such that, when combined with the other equation, one of the variables is eliminated?

Multiply the second equation by - 1 to get - 2x - 7y = - 28

Multiply the second equation by - 4 to get - 8x - 28y = - 112

Multiply the first equation by - 7 to get - 28x - 7y = - 28

Multiply the first equation by - 2 to get - 8x - 2y = - 8
