Can there be more than one answer to a balanced equation?

can there be more than one answer when balancing equations?

i have an equation that is supposed to be balanced using oxidation number.

ClO- + (S2O3)2- + OH- -> Cl- + (SO4)2- + H+

the answer is
4ClO- + (S2O3)2- + OH- -> 4Cl- + 2(SO4)2- + H+

but I got

2ClO- + (S2O3)2- + 3OH- -> 2Cl- + 2(SO4)2- + 3H+

as far as I can see both are balanced is one more correct than the other???? please help!!!!
