Maths Olympiad Daily Problems

This is a set of 3 good algebra problems and I would like you all to solve by abstract and elegant methods rather than old traditional methods,Brute force and unnecessary manipulation without any justification should be avoided and I will post the solution on 10th March , and the first solver of these questions will get something from me (obviously not money as I am unemployed but something valuable) , please do pay attention to the heading of the question they may serve as a hint for begginers. Enjoy 😜
