can someone please Help!?

Select the choice below that could be the first step in solving the following system of equations using elimination:
-6x − 7y = 12
3y − 4x − 1 = 0

Replace the right side of the first equation with the second equation.

Multiply the second equation by 4.

Multiply the second equation by -3.

Write the second equation in terms of y.

In elimination, you want to make either x or y disappear by making it cancel out.  The -6x and -4x have a common multiple of 12.  Your goal is to make both into 12x but one needs to be positive and the other negative...
