### Differential Equation

Ok, so I really need help with this one;

I need to show that y=x * lnx is a solution to the differentialequation y'-(y/x)-1=0

Any help would be really appreciated!

### Re: Differential Equation

Integrating both sides,

logy=log(x-1).

Thats what I get

Character is who you are when no one is looking.

I'm rather unfamiliar with these concepts. (Beginner) What does dx stand for?

### Re: Differential Equation

And how did you integrate the sides? Is there a formula for this? For future reference.
