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: P_14(j) or ~q. forall x_14: P_14(x_14) <-> Q_14(x_14). Q_14(j) or q.
q -> P_14(j) can be inferred via the rewriting rule. forall x_14: P_14(x_14) -> Q_14(x_14) can be inferred via the universal biconditional elimination rule. forall x_14: Q_14(x_14) -> P_14(x_14) can be inferred via the universal biconditional elimination rule.
