    First order differential qusetion [urgent]

    1. The problem statement, all variables and given/known data
    Question 7

    2. Relevant equations

    3. The attempt at a solution
    I can do part a)

    and i can begin part b, using seperation of variables I get:

    1/4 ln |1+2v| = ln|x| + C

    but how do i use this to solve equation I

    Thanks :)

    Once you get v(x)

    just substitute the known relationship v = y/x
