1. ## y'-xy+x/y =0

y'-xy+x/y =0
i spitted it into
(xy+x/y)dx +dy=0
i tried to solve it by finding integration coefficient
but it gives me

m'+(1-1/y^2)m/(y+1/y)=0

i there any other way
cause i even cant find the integration coefficient

2. It's separable. I would do it that way.

3. thanks

4. You're welcome!
