Given a equation , let’s find the real value of x.

First, divide both sides by which becomes:

as , and , it becomes:

Let’s replace with and further we have:

that is

This equation has a golden root (the negative root should be discarded):

Therefore,
and
and
and we can compute the value x that is approximately 1.187.
