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: forall x_10: ~R_10(x_10). R_10(a_10) <-> p.
R_10(a_10) -> p can be inferred via the biconditional elimination rule. p -> R_10(a_10) can be inferred via the biconditional elimination rule.
