The oxidation number of the elements should be equal to zero or the charge of the compound when summed together. In this case, the overall charge is zero. Oxygen has a charge of - 2, a total of - 6, H has charge of + 1, a total of + 3 so B must have a charge of + 3 to make the overall charge equal to zero
