How to solve this kind of equation $({x}^{y}={y}^{x})$$({x}^{y}={y}^{x})$

I'm little bit stuck with this system of equations :

${x}^{y}={y}^{x}$ and ${x}^{3}={y}^{2}$

An obvious solution is $(x,y)=(1,1)$ but what about the solution $(9/4,27/8)$?

I know the relation ${a}^{r}={e}^{r\mathrm{log}a}$ but it doesn't help me.

Thanks

I am having some confusion about holes in rational functions. As I'm aware, a hole is where both the numerator and denominator become zero due to some discontinuity. For example,

$f(x)=\frac{(x+1)(x-1)}{(x+1)}$

would have a hole at $x=-1$.

What is the point of distinguishing between a hole and Vertical Asymptote?

What is the logic behind the numerator needing to having a discontinuity at the same point as the denominator?

$f(x)=\frac{(x+1)(x-1)}{(x+1)}$

would have a hole at $x=-1$.
