    [HELP!] A Confusing Optic Problem

    1. The problem statement, all variables and given/known data
    Prove that, according to the figure below:


    2. Relevant equations

    3. The attempt at a solution
    I've been using the basic equation above (the integrated lenses with radius r1 and r2) but it's still confusing. Is it the total focus of the lens is 1/f = 1/f1+1/f2? And should I substitute it into the relevant equation above? After all, I still can't proceed, because I don't know what should I do next :(
