Show that the argument form with premises (p∧t)→…¬s and conclusion q→r is valid

$begingroup$


Stuck on this problem. I want to use the rules of inference to show that the argument form with premises (p∧t)→(r∨s), q→(u∧t),u→p, and ¬s and conclusion q→r is valid. Would really appreciate if someone can help me solve it and explain which rules they used
