Solving Equations with Special Cases

Hello everyone! For this assignment, you MUST show all work in your notebook. I am going to be checking when I get back, and no work = no credit. If you showed your work, the grade you earn on this assignment will be put into the gradebook. You can redo this Quizizz as many times as you need to get a grade of 90 or above. Try your best & use the examples I left on the board to help you!

Do you have your notebook & a pencil?

• Yes! I'm ready to begin and show ALL work in my notebook!

• No, I didn't even read any of that and I want you to give me a 0 on this assignment.
