1. The problem statement, all variables and given/known data

I solved this equation and I was wondering if it's correctly solved...Also, I have one question: In my equation,at the very end, is it possible to calculate the value of V?I have solved other exercises where the final equation was,for example: y + ln[y - 1] = ex + C . Is it possible to simplificate it more?

2. Relevant equations

3. The attempt at a solution

I think the reason that noone has helped is that the attachment is still pending approval. You may have to wait a while for it to be approved.

You have a couple of missing negatives: at one point $-(1-\frac{1}{v}$ becomes $-1-\frac{1}{v}$. I would recommend that you rewrite -(1- v) as v- 1.

In this case, no it is not possible to simplify it any more. That's typical separable differential equations- you cannot generally solve for one variable as a function of the other.
