The standard approach for solving the DE...

(1)

... has as first step the division of both terms of (1) by obtaining...

(2)

... and then the substution...

(3)

... so that the new DE in z is...

(4)

... which is linear and easy enough to solve...

... the minor problem is that (4) seems not the same You obtained that is...

(5)

Kind regards

I fixed that step, although I am still having trouble finding the correct answer.

Original DE:

I incorrectly typed the answer the professor gave me in my first post. The answer he gave is:

From equation (5) to (6). Why did you goe from 2/x to 2/3?
