You need to give the f(x) function or else this is not solvable
ANSWER
The substitution property of equality.
EXPLANATION
We know that:

and that

Since x=5 or 5=x , we can substitute x for 5 wherever we see x in the given equation.
When we do that, we obtain;

This is what we refer to as the substitution property of equality.
I honestly do not know what to say here: it's already in decimal form. Please, if you made a mistake while typing in the problem, tell me.
