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: w -> Q_14(a_10). u_1 -> w. forall x_14: P_14(x_14) <-> Q_14(x_14).
u_1 -> Q_14(a_10) can be inferred via the transitivity 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.
