Oxidation states for Oxygen

How would you figure out what the change in oxidation state is for a reaction where ? There's no charge there so I could only assume the oxidation states are both 0, but that would not make sense.

One of the UAs told me that in order to figure out if O3 is being oxidized or reduced, you would need to know if the other element in the equation is being reduced or oxidized. For instance, if you had O3 + Br- -> O2 + BrO3-, Br- is being oxidized. Thus, if Br- is oxidized, that means O3 must be reduced.

And after that, you would add the appropriate number of electrons to cancel out the positive Hydrogen ions?

I think I understand now, thank you(:
