dont know what to do although a worked example is given on what i need to do, please help

Tho two hal equations ate added togethot so that the electons canoel out: 6.g. combine MnOr+8H++5sMr2+4HO and 2Cr+Ch2+2a Tho first equebion hes 5 electrons and the second has 2 electons. To balance these cot, moiligil the first by 2 (fo griv 10 eiectrons) and the second by 5 (lo give 10 elowtions) x22MnO4+10H++10e2Mn2++BH2Ox510Cl5Cs+10enombining2MnOH+16H+1ge+10CH2M2+8HCO+5Ch+19H4finalanswer2MnO4+16Hf+10Cr2Mt2+BH6+5Cb Look at the following hay equations.
