Real gas problem

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

    The task is the following:


    2. Relevant equations

    3. The attempt at a solution

    I calculated the derivatives for Vm (crit) and set them = 0, but somehow I can't solve the equation to obtain Vm (crit) on one side alone.

    This is how far i managed to do it:


    Can someone help me?

    One approach: For each equation move the second term on the left to the right side. Then divide the two equations.
