Answer:

B.)

Explanation:

B.) Multiply the top equation by 3, multiply the bottom equation by -2, then add the equations.

When you multiply the top by 3 you'd get 6x+24y=-9 and when you multiply the bottom equation by -2 you'd get -6x-12y=8

6x and -6x would cancel each other out eliminating the x variable.
