Answer:
I believe the answer is c. The second equation in system B is -7x = 14. The solution to system B will be the same as the solution to system A.
Step-by-step explanation:
So, the question is saying that to get system B, replace the second equation in system A, 3x - 2y = -11, with that (3x - 2y = -11) added to the first equation. And multiply that by -2. So that looks like this: 3x - 2y = -11 + 5x - y = -11 × -2. When solving that, the solution for x is -2. So the solution to both systems is x = -2. That eliminated the top choices. So now, plug in the x for the remaining solutions and the answer is C. -7(-2)= 14.
