[tex]\frac{dy}{dx}=\frac{xy+3x-y-3}{xy-2x+4y-8}[/tex](adsbygoogle = window.adsbygoogle || []).push({});

I want to solve this DE using the separation technique. Any ideas on how to start?

And just for myself, and maybe anyone else. Is there a sort of systematic approach to finding out how to start these problems? It seems like I will work a few no problem, then get to one and just stare for awhile. Maybe if there was some sort of method to the madness, then it might make things easier. Just a thought.

Thanks!
