I was wondering given a function like $f(x) = x +5$ that for a given $x$, the value will be the same.

I don't understand the question. Can you please try to clarify? –  Git Gud May 6 '13 at 21:41
You will need to be more clear. Note that $x$ and $x+5$ are never equal. –  Will Jagy May 6 '13 at 21:41

It is called a fixed point. Your example does not have any, because $x \neq x+5$ for any $x$. But if we had $f(x)=5-x$, we could find that $f(\frac 52)=\frac 52$
