Math Exam tomorrow (elementary algebra) help :(

Hi guys,

I have a Math final worth 100% of my grade and have been knee deep in my text book for the past 2 weeks. I went to the copy centre beside my University and they had old copies of finals, and my friend who did the Math final last year said she used the old exams to study and they're almost identical each year (except obviously the values of the numbers changed etc).

I scanned the most recent exam from last term and would really appreciate if someone could outline the basic way to deal with the questions. Anyway this is the exam PDF, any form of help is appreciated.

Appreciate any advice/help. Thank you!
