In most cases, yes. Just focus on flipping the reactions so you have the correct overall reaction equation (one half-reaction must be a reduction, the other an oxidation, and when added together, they must be equivalent to the original reaction).
In addition to what was said above, make sure when you add the two half reactions together the electrons cancel out. This helps on the idea of flipping reactions because in one half reaction the electrons must be on the reactant side and in the other half reaction the electrons must be on the product side.
This is only true in a GALVANIC CELL - where the chemical reaction is spontaneous. In an electrolytic cell, this is not what we would do (we'd actually do the opposite I'm quite sure), because the reaction is non-spontaneous.
