What can be inferred from the following premises in a single inference step (ignoring inferences that add new predicates or constants)? Name the inference rule being used: p_7 <-> q_7. p_14 and w_3. ~p_7.
p_14 can be inferred via the simplification rule. w_3 can be inferred via the simplification rule. p_7 -> q_7 can be inferred via the biconditional elimination rule. q_7 -> p_7 can be inferred via the biconditional elimination rule. ~q_7 can be inferred via the biconditional elimination rule.
