How do I find x as a function of x? Sorry for the title, I don't know how else to put this into words.
Basically I wanted to know how to get the result below:

I have no idea about why the graph is showing X as a diagonal line. How can X by itself be a line which is not constant?

$$x=462+0.085x$$
$$(1-0.085)x=462$$
$$0.915x=462$$
$$x=\frac{462}{0.915}=\frac{30800}{61}$$
