Changing the subject in formula editable PowerPoint grade 9 / grade 10

This editable PowerPoint presentation covers the topic: How to change subject in a formula. Operations range from adding to square root. The main idea is, that examples should be accessible for everybody, but question slides are divided in three parts: Easy, medium and challenging. The idea with this is that a student should be able to choose the right level of challenge.

Questions in the slides have answers. This might take 40 mins but I would add some extra work for longer lesson/fast students. Multiple choice questions are a fast way to check understanding before proceeding. This is suitable for years 9 or 10 depending on the curriculum. Common core HSA-CED.A.4. There are 18 slides.
