Solve the following DE:
$$(1-3/y+x)dy/dx+y=3/x-1$$
I got
$$\Psi=xy-3\ln(x)+x+y+3\ln(y)=c$$
using the Exact equation method.
Is that correct?

I got 
$$\Psi=xy-3\ln(x)+x+y+3\ln(y)=c$$
using the Exact equation method.

I got some different signs in my answer.  I got xy-3in(x)-x+y-3ln(y)=c
im going over my work right now

anonymous · Answer

sorry, that in(x) should be an ln(x)

anonymous · Answer

It probably should be a positive since it's coming from the "+x", but check just in case. Thanks

anonymous · Answer

i made a mistake, i now got xy - 3ln(x) + x + y - 3ln(y) = c

anonymous · Answer

yep, that's right joe

anonymous · Answer

Yeah, you're right.  I stuck a +in there. So close!
