The question is why can't you balance it? First,consider the Fe. You have 2 on the right side and one on the left,so you have to add a second on the left. Now the oxygen. You have three on the right. However, oxygen gas is a dimer, so a simple balance would give you 1-1/2 on the left. However, chemists frown on fractions (they are really stupid), so we put 1-1/2 on the left and multiply everything by 2, and get.....
4 Fe + 3O2 -> 2Fe2O3

Iron can be +3, O is -2.
O3 is then -6
Fe2 is +6
so:
4Fe + 3 O2 --> 2Fe2O3
