Are these equations equal if you divide by $r/n$?

I have two equations

$$\dfrac{\dfrac{P}{1-(1+\frac rn)^{-n}}}{\frac rn}=x$$

and

$$\dfrac{P\cdot\frac rn\cdot(1+\frac rn )^n}{(1+\frac rn)^{n}-1}= x.$$

If I put in an amount for $P$, $r$, and $n$ I get the same answer in each formula but I cannot figure out how to simplify the second one to see if they are truly the same formula in different formats.

Firstly I replace $r/n$ by $t$. The LHS of the first equation is

$$\frac{P}{\frac{1-(1+t)^{-n}}{t}}$$

In order to divide $P$ by the fraction we multiply $P$ with the reciprocal.

$$\frac{P\cdot t }{1-(1+t)^{-n}}$$

Expanding the fraction by $(1+t)^{n}$

$$\frac{P\cdot t \cdot (1+t)^{n} }{(1+t)^{n}-1}$$
