Chem Help!?

Question

The following equilbrium partial pressures were measured at some temperature at some temperature
NH3-->0.310 atm
N2-->0.180 atm
H2-->0.150 atm

2NH3 <-> N2 + 3H2

In a different experiment at the same temperture, the equilibrium pressure of N2 was found to be 0.180atm and that of H2 to be 0.350 atm. What is the equilibrium pressure NH3 if K = 5.490 for the above reaction at the temperature of the equilibrium?
P(NH3) = ______atm

Please Help By Explaining!!

Ummm.... Shouldn't you just ask your chemistry teacher for help? Usually your teacher will do the whole problem for you anyway when you ask for help ;)
