How to Balance Atoms in Ion-Electron Method?

[Aafia]

In ion electron method to balance equation we have to follow steps ... i am doing it but here i am confusing how to do this ...
There are two partial equations i have made in basic medium
1- H2PO2---------> H2PO3^-1
2-Fe(OH)3---------->Fe(OH)2
Now the second step is to balance the atoms
By adding 2OH for Oxygen and H2O for Hydrogen
But it can't solve
Helpp me pleasezzzz
Thanks

Show how you approach the first reaction.

Show how you approach the first reaction.

I had a full reaction
H2PO2+Fe(OH)3------->H2PO3^-1+Fe(OH)2
Then i split it into two partial equations according to rule ..

Show how you are trying to balance first (or second, whichever you like) half reaction.
