$${\frac{{\mathtt{5}}}{{{\mathtt{9}}}^{{\mathtt{x}}}}}{\mathtt{\,-\,}}{\frac{{\mathtt{1}}}{{{\mathtt{9}}}^{{\mathtt{y}}}}} = {\mathtt{7}}$$

Because we have two variables and only one equation, we will have infinite solutions......here's a graph....https://www.desmos.com/calculator/quay485peu

Interestingly, the graph has an asymptote at x = 0, but it only exists on the left side of this asymptote......also.....the graph looks as though it has almost a linear form when x is less than about -1
