Ice Tables

After calculating x in the ice table, in what instance would we plug the x back into row E?

I do not fully understand the scope of your question but I'll answer to the best of my ability. If they ask for final equilibrium concentrations and you begin with a certain amount of reactant, lets say 0.1, then the E section for that reactant would be 0.1-x, so you would plug x back in to find the equilibrium concentration of that reactant.

If the initial concentration (the I column) is 0, then the E column will end up either being x or -x. If the initial concentration is not 0 (lets say it is "a"), the E column will end up being either a-x or a+x.

Your E row represents the expressions of change the species goes through inorder to reach their equilibrium points. After you calculate x or the change, you plug that into the E row and there you the concentrations of the species at equilibrium.
