    In the second equation, solve for \dfrac{1}{p}.

    First q = \dfrac{9}{2p}. Then, multiply both sides by \dfrac{2}{9}. So, \dfrac{2q}{9} = \dfrac{1}{p}. Then \dfrac{2q}{9} + \dfrac{1}{q} = 1. Now, solve for q.

    Re: help

    Note: There are a number of ways to solve the system of equations. You first need an expression for p in terms of q, so in the first equation, you could multiply both sides by pq. Then q+p = pq. Now, solve for p:

    p-pq = -q

    p(1-q) = -q

    p = \dfrac{-q}{1-q} = \dfrac{q}{q-1}

    Plug that into the second equation and solve for q.
