How can i find all integers to this equation?(adsbygoogle = window.adsbygoogle || []).push({});

3(x+y)-xy=0

I allready found just by tring that if x=y then its 6 and x=12 ,y=4 (x=4 and y=12)

I think that there are more, but how can i find all of them?

PS. the first task was: 1/x + 1/y = 1/3 and then i had to find all integers.

Thank you for your help!

Sorry for my bad english.
