Answer:
A. the x-coordinate of the intersection point
Step-by-step explanation:
If you are solving ...
f(x) = g(x)
the solution is one or more values of x. That is still true if you rewrite the equation to be a system of equations ...
y = f(x)
y = g(x)
The value of y tells you the value of each side of the original equation where the solution causes the functions to be equal. That is largely irrelevant. What you're looking for is the value of x.
The solution is the x-coordinate of the intersection point.
