Thanks P.

Please help by showing your work for the following practice problems, preferably handwritten so I can visually understand your though process. Thanks 

P.S:I have asked this question 3 times now and no one has helped me, I don't understand what the issue is because I asked a similar question before and it got answered, this is NOT for hw so I am not cheating! Tutors are supposed to help with problems I cannot understand so please do so instead of making me ask the question over and over. Thanks!
