  1. CaCl2 (aq) + Na3PO4 (s) >> Ca3(PO4)2 (s) + NaCl (aq)

    Balancing it is easy. go to the most complicated formula, and wort from there.

    it is Ca3(PO4)2

    so you need three Ca on left then.

    3 CaCl2 + Na3PO4 >> Ca3(PO4)2 + NaCl

    Now consider the phosphates in the complicated calcium phosphate: two of them.

    3CaCl2 + 2Na3PO4 >> Ca3(PO4)2 + NaCl
    now clean it up. first, Cl
    you need two Cl in NaCl...
    3CaCl2 + 2Na3PO4 >> Ca3(PO4)2 + 2NaCl
    done. reinsert the states from above.

  2. but that's wrong because sodium is not balanced

  3. Right. You need six NaCl. sometimes we introduce obvious errors to keep student from copying and pasting.
    Good work.

  4. but that's my problem I don't know how to get Na balanced
