Consider the following premises. ~u. forall x_13: S_3(x_13) -> Q_13(x_13). forall x_13: Q_13(x_13) -> R_13(x_13). R_13(e) -> S_3(e). u <-> S_3(e). Can we infer forall x_13: S_3(x_13) -> Q_13(x_13) from them? If possible, name the inference rules being used at each step.
That is one of the premises. Therefore, the answer is yes.
