A system of equations and its solution are given below. System A
5x-y=-11
3x-2y=-8
Solution: (-2,1)

To get system B below, the second equation in system A was replaced by the sum of that equation and the first equation in system A multiplied by -2.

System B
5x-y=-11
?

A. The second equation in system B is -7x = 14. The solution to system B will be the same as the solution to system A.

B. The second equation in system B is 7x = 30. The solution to system B will be the same as the solution to system A.

C. The second equation in system B is -7x = 14. The solution to system B will not be the same as the solution to system A.

D. The second equation in system B is 7x = 30. The solution to system B will not be the same as the solution to system A.
