Choose the equivalent system of linear equations that will produce the same solution as the one given below.

6x + 2y = -6
3x - 4y = -18

12x + 4y = -12
15x = -30

8x + 4y = -4
14x = -10

6x - 8y = -36
-6y = -42

6x - y = -15
3y = 9

I think the first step would be to solve the given system of equations. Since each of the choices have an equation with just one variable, it should be easy to check which is the same.
