7. Simplify each of the following to p, q, T or F using logical equivalences. State the equivalence used at each step. Do not skip steps. You can only use one equivalence or definition per step (even if the same one can be applied multiple times). Do not forget about the double negation law. (a) q→ (pvq) (b) (p→q) ^ (p → ¬q).
