It's just making sure that you have the same number of each atom on both sides of the equation. The first thing I notice is that one side has 4 phosphorus atoms, so I'd start by giving H3PO4 a coefficient of 4. That means your whole H3PO4 is multiplied by 4, so you have 16 product oxygen atoms. P4O10 has 10, so giving water a coefficient of 6 balances your oxygen. Both sides now have 12 hydrogens, so you're done.

P4O10 + _6_H2O --> _4_H3PO4

makes 4 equal P's, 16 equal O's, and 12 equal H's.
