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: ~q_17. w <-> q_17. q and s.
q can be inferred via the simplification rule. s can be inferred via the simplification rule. w -> q_17 can be inferred via the biconditional elimination rule. q_17 -> w can be inferred via the biconditional elimination rule. ~w can be inferred via the biconditional elimination rule.
