3NaOH(aq)+H3PO4(aq) ==>Na3PO4(aq)+3H2O(l)
Did you want this balanced. I have corrected the symbolism for the arrow and corrected the aq (from pq for Na3PO4.
NaOH(aq)+H3PO4(aq)�¨Na3PO4(pq)+H2O(l)
Please help.

Yes I have trouble with balancing equations(in general).
Don't make it harder than it is. It's just a matter of counting. Here is how I do the NaOH + H3PO4.
NaOH + H3PO4 ==> Na3PO4 + H2O
1. Look at the equation. The first thing I see is 3Na on the right so I make 3NaOH on the left to balance Na. I also note the 1 PO4 on the right which means the 1 now for H3PO4 should be correct.
2. With NaOH, H3PO4, and Na3PO4 now set, that leaves only one item which is H2O. Count how many H atoms on the left. I see 6. That means 3H2O.
3. Then I check everything to make sure it is balanced.
3Na on left and right
1 PO4 on left and right
6 H on left and right
3 O atoms (excluding those due to PO4) on left and right. You CAN count all of the O atoms but I think it makes it a little easier if we keep PO4 together.
