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: R_7(g) -> S_14(a_14). forall x_7: R_7(x_7) <-> S_7(x_7). ~R_14(a_14). forall x_14: R_14(x_14) <-> S_14(x_14).
forall x_7: R_7(x_7) -> S_7(x_7) can be inferred via the universal biconditional elimination rule. forall x_14: R_14(x_14) -> S_14(x_14) can be inferred via the universal biconditional elimination rule. forall x_7: S_7(x_7) -> R_7(x_7) can be inferred via the universal biconditional elimination rule. forall x_14: S_14(x_14) -> R_14(x_14) can be inferred via the universal biconditional elimination rule.
