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_16: W_2(x_16) <-> S_3(x_16). forall x_16: ~P_10(x_16). exists x_16: P_10(x_16).
forall x_16: W_2(x_16) -> S_3(x_16) can be inferred via the universal biconditional elimination rule. forall x_16: S_3(x_16) -> W_2(x_16) can be inferred via the universal biconditional elimination rule.
