We are given that

.
Substitute x with 5-x, then the above equation becomes:

, that is

So, we have the following system of equations:
i)

ii)

multiply the first equation by -4, so that we eliminate f(5-x)'s
i)

ii)

adding the 2 equations side by side we have:

expanding the binomial, and collecting same terms we have:


dividing by -5:

dividing by 3:
