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(a_10) <-> S_10(a_10). forall x_10: Q(x_10) -> S_10(x_10).
Q(a_10) -> S_10(a_10) can be inferred via the biconditional elimination rule. S_10(a_10) -> Q(a_10) can be inferred via the biconditional elimination rule.
