    [SOLVED] SAT math page 682 #12

    If n=3p, for what value of p is n=p?
    a)0
    b)1/3
    c)1
    d)3
    e)e can never equal p

    I honestly think a,b,c,d can all be correct since it has to depend on what n actually is. Any tips in solving this problem? (:

    If n=p, then n=3p can be written : p=3p. This makes 2p=0

    If p=1/3, then n=1, which are different. So it cannot be solution ! same thing for c) and d)
