Electrons should be balanced after all elements have been balanced. The number of electrons in each half-reaction should be equal, so if they are not equal, multiply the equations by a coefficient to make them so.
You follow the order in the previous posts but you don't balance electrons. Electrons are used to balance the charge of the reaction. Electrons are then balanced (by multiplying either the reduction or oxidation reaction) so that they cancel out in the redox reaction to show the transfer of electrons & ensure elements, charges, and electrons are balanced.
