    SO here is the problem

    I am wondering how to make J the subject ?

    I have tried making J/2 and 4a/3 into a single fraction but so far nothing.I am doing something wrong somewhere.

    Here it is so I can see it better:
    [tex]V = \frac{\frac{J}{2} + \frac{4a}{3}}{L}[/tex]

    Multiply both sides by L.
    Subtract 4a/3 from both sides.
    Multiply both sides by 2.
