Consider the following premises. p_10 or ~p. p_10 <-> p. Can we infer p -> p_10 from them? If possible, name the inference rules being used at each step.
 From p_10 <-> p we can infer p_10 -> p via biconditional elimination. Finally, from p_10 or ~p we can infer p -> p_10 via rewriting. Therefore, the answer is yes.
