The problem is Na3PO4 + BaS

I know that equals Na3PO4 + BaS = (Na3)2S + Ba3(PO4)2

This is where I am stuck. I am trying to rework this for practice for my quiz. I know the final answer should be 3Ba + 2PO4= Ba3(PO4)2 but i cant seem a way to get to that. Every time i try to balance the equation it gets jumbled up. If you could respond with your step by step process I would greatly appreciate it.

My attempt at balancing it is 2Na3PO4 + 3BaS= (Na3)2S + Ba3(PO4)2  BUT THIS ISN'T RIGHT! The S isn't balanced. But rebalancing it jumbles it up.

3Ba + 2PO4= Ba3(PO4)2

Ignoring charges is a sure way of making mistakes.
