Solving the system of equations, it is found that x = 3, that is, there are 3 128 MB memory sticks.
--------------------
We want to solve for x, thus, in the first equation, we write y as a function of x, that is:

Replacing in the second equation:





x = 3, that is, there are 3 128 MB memory sticks.

(f-g)(x) = x²+6x - (7-x)
(f-g)(x) = x² + 6x - 7 + x
(f-g)(x) = x² + 7x - 7
(f-g)(9) = 9² + 7*9 - 7
(f-g)(9) = 81 + 63 - 7
(f-g)(9) = 137
