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)

Thanks again Moo! You rock!!
