Hello, I'm going to attach the question as a picture. Please also show easy-to-understand steps. Still, if specific problems need a little explanation, then a tiny description would be much appreciated and clearly label the answer. Please take your time when answering the question. Unfortunately, some tutors have given me the wrong answer, so take your time. I hope that's not too much to ask for but thanks in advance!
