Hello, there is another AC circuit that I tried to analyze with nodal analysis, and again came up with a different answer than the book. Could someone please look at the attached and tell me where I might have gone wrong? Again, thank you.

 

I don't think anyone is going to go line-by-line debugging your math. It's most likely a sign error or an addition/subtraction error.

Explain how you came to your main equations to see if your thought process is correct.
