Solve the following system of equations using the elimination method.

2x + 4y = 10

-2x + y = - 15

Question 10 options:

A)

(-2,7)

B)

(7,-1)

C)

(3,1)

D)

(8,-3)

The answer would be B, (7,-1) because of what happens when you plug in the numbers. For the first equation, 2x+4y=10 would become 2 (7) + 4 (-1) = 10 which turns into 10=10 resulting in a true statement. For the next one, - 2x+y=-15 which becomes - 2 (7) + (-1) = -15 which results in - 15=-15 meaning B is the true answer for both equations
