Answer:
Step-by-step explanation:
We have to find the system in which we can use the x and y from the given system of equations and make it hold true
From the given equations:
multiply top equation by -2 and add them
so, x = 6, y = 5
A: x-y = 2
6 - 5 = 1, so its not a
B: -2x + 2y = -2
-2(6) + 2(5) = -12 + 10 = -2
B works
just looking at C and D I can tell it doesnt work
So the answer is B
