Faucets $$X$$ and $$y$$ dispense water at their respective constant rates. Dispensing simultaneously, faucets $$X$$ and $$Y$$ fill an empty tub in 3 minutes. Faucet $$X$$, dispensing alone, takes $$\frac{3}{4}$$ as long as faucet $$y$$, dispensing alone, to fill the empty tub. Let $$x$$ and $$y$$ be the respective times, in minutes, that it takes faucets $$X$$ and $$y$$, each dispensing alone, to fill the empty tub. What are the values of $$x$$ and $$y$$?
