Question

Please Help! Middle school algebra, don't understand!
Ok so our teacher gave us this assesment out of the blue. We did not learn this at all, and it all looks like a foreign language to me. Can someone please explain to me how to do this?! Oh and the answers on the first page are guesses, they probably aren't right to so please don't judge me on them!

Thank you so much! Oh and this is my first question on here, so I apologize if I did anything wrong..

Answer 2

Let's look at 1a first
