* Division by a variableneeds a case distinction.
* You might also be removing a solution when dividing by a variable.

Are x,y elements of the Real Numbers.
Is a integer or a real number or a complex number solution desired?

Are we even operating on Real Numbers (and associated operations and comparison rules?)

>>8921400
Yes that looks fine

Shouldn't the right side be lny - (y/x)? Also in line 3 you forgot to add the derivative tickmark to the first y

>>8921400
looks right to me
you can solve for y with the Lambert W function, which is the inverse function of x*e^x

>>8921400
you forgot a minus sign in front of y/x in line 4
