Balance the following redox equation, using either the oxidation-number-change method or the half-reaction method. You must show all your work, especially the total number of electrons transferred in the reaction. (In using the half-reaction method, assume that the reaction occurs in an aqueous acid solution.)

Question

Balance the following redox equation, using either the oxidation-number-change method or the half-reaction method. You must show all your work, especially the total number of electrons transferred in the reaction. (In using the half-reaction method, assume that the reaction occurs in an aqueous acid solution.)
Fe2O3 + CO → Fe + CO2 (acid solution)

What's your problem here. Those methods have rules and just need to follow the rules.
