SOLUTION





The format of the preceding proof is important.
You must write a coherent sequence of propositions, each of which is equivalent to the previous one, due to the application of an equivalency law; at each step, the appropriate law must be cited (except that we will not need to cite Double Negation when it occurs within the application of another law).
