Question

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 not be the same as the solution to system A.

B.

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

C.

The second equation in system B is 7x = 30. The solution to system B will 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.
