The Attempt at a Solution


View attachment 231065
This is how I obtain the answers, which I checked all the calculations and I don't think there is numerical problem. I followed the steps in the solution manual, yet I am wrong and I don't know why.

Can anyone see anything going wrong here?
thank you so much!

The rules say that images should not be used in place of text. They can be hard to read for people using phones to access PF, but your images are pretty clear, so we'll allow them.

When you compose a new post, a button "LateX" at the lower left allows you to enter math directly.
