If f(x)=5x-12, find a value for $x$ so that $f^{-1}(x)=f(x-1)$.

so first, find the inverse function of f(x) = 5x - 12, which just switch the x and y values, and then solve for y. After that, we replace the inverse function we solved for $f^{-1} (x)$. then sub in x - 1 for f(x). then solve the 3-step equation. I think you can use this information to solve the problem.
