Final answer:

To solve the system of equations using elimination, multiply the first equation by 6 and the second equation by -8 to eliminate the x variable. Subtract the second equation from the first equation to eliminate the x variable. The solution to the system of equations is (-7, -8).

Step-by-step explanation:

To solve the system of equations using elimination, we need to eliminate one of the variables by adding or subtracting the equations. Multiply the first equation by 6 and the second equation by -8 to eliminate the x variable.

Doing this, we get -48x - 60y = 144 and -48x - 40y = -16.

Subtract the second equation from the first equation to eliminate the x variable. This gives us -20y = 160. Solving for y, we find that y = -8.

Substitute the value of y into either of the original equations and solve for x. We find that x = -7.

Therefore, the solution to the system of equations is (-7, -8). So, the correct answer is A. (-7, -8).
