you do realize that this is an equation for a hyperbola, and as a result has an infinite number of solutions for (x,y) ... ?

I know the answer . y= 20^ . x is ( 7 x 7 )=49. But is there is a method to do it . But the way what is hyperbola .

that is not the only solution. for example ...

$x = \sqrt{5} \, , \, y = 2$
