Does anyone have a book that can make you cry? 😅

It seems this girl is very emotional and introspective.

I’m trying to solve these questions, but I’m getting confused about the steps shown in my notebook. I’ve attached my working. Can someone point out exactly where I’m going wrong and explain the correct method? I want to understand the concept, not just get the final answer.
