Choose a method that can be used to solve this system of equations by elimination.

2x – 2y = 24
4x + 7y = –40

A. Subtract 2x from both equations and solve the first equation for y.

B. Multiply the first equation by –2 and add the second equation.

C. Add the first equation to the second equation and subtract 6x from both
sides of the equation.

D. Subtract 7y from the second equation and add the first equation.
