Decide every function f, so that:

f(x) + 2*f(3-x) = x^3

Now, what I thought could work, was to try and find an equation for f(x) by integrating. However I can’t understand how I am supposed to do it. The 2*f(3-x) also really throws me off, as I’m not so familiar with translations(? I’m not sure if it’s the right word in English?). Any help or tips on solving the problem I would be grateful for!
