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: forall x_10: P_10(x_10) -> P(x_10). forall x_10: ~P(x_10). exists x_10: P_10(x_10) <-> W(x_10).
forall x_10: ~P_10(x_10) can be inferred via the universal modus tollens rule. exists x_10: P_10(x_10) -> W(x_10) can be inferred via the existential biconditional elimination rule. exists x_10: W(x_10) -> P_10(x_10) can be inferred via the existential biconditional elimination rule.
