Hello. I keep getting lost on my process and keep getting wrong answers. I'm having trouble getting the q points and I'm possibly getting the polarity wrong in my equations. How would you go about this?

Thank you for your time and help. I know it is a lot so if you could just do the first couple so I can see what is going on, I'ld appreciate it very much.
