Answer:

Answer choice a.

Step-by-step explanation:

Let's do part of the work of solving the given system:

6x + 2y = −6

3x − 4y = −18

Multiply the first equation by 2 so as to make the coefficient of y = to 4:

12x + 4y = -12

Combine this result with the second equation:

12x + 4y = -12

3x − 4y = −18

------------------------

 15x = -30

Note that these results are precisely the same as the equations in Answer Choice a.
