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: S(a_10) <-> Q_3(a_10). forall x: S(x) -> Q_3(x).
S(a_10) -> Q_3(a_10) can be inferred via the biconditional elimination rule. Q_3(a_10) -> S(a_10) can be inferred via the biconditional elimination rule.
