Default Request for helping to solve the problems in vol. 1

I received the vol. 1 book a couple months ago. I like the book but there are several problems that I could not solve. Could anyone offer help? Here are the pictures that I have solved so far (which are in page 97, 125, 138 and 198 respectively), thanks!
