Determining a solution (an ordered pair) from a system of equations.

If f(x,y) and g(x,y) form a system of two equations in two variables, x and y, such that:

f(x,y)  = 2x2 + y = 0
g(x,y) = 3x - 2y - 7 = 0

Which of the following ordered pairs (a,b) is a solution of the system?

A) (2,-8)
B) (3,1)
C) (1,-2)
D) None of the above
