Solve the system of equations and check your answer(s). You may use any method to solve.

2x^2 - y = 8

7x + y = -4

I tried it this way:

y = -7x - 4

2x^2 - (-7x - 4) = 8

2x^2 + 7x + 4 = 8

2x^2 + 7x - 4 = 0

(2x -1) (x + 4) = 0

x = 1/2, -4

Now, when I plug in both values for x (because there were 2 values) seperate times i get values for y that don't check out when I check both values for x and y. HELP!!! Thank you so much!
