Solve the system of equations and choose the correct ordered pair.

2y = 4x + 8
4y = 4x + 20

L.H.S is already equal, so just subtract 1st equation from second, 
2y = 12
y = 6

Now, substitute it in 1st equation, 
2(6) = 4x + 8
4x = 12 - 8
x = 4/4
x = 1

In short, Your Answer would be Option C) (1, 6)

Hope this helps!
