Substitution & Re-arranging formulas starter.
Hi, just a couple of PowerPoints that I'd made up during my teacher training. Good for classes that have covered re-arranging and also substitution.
The substitution powerpoint has many questions with unknowns, there is one question with only 1 unknown, so once you&'ve solved it you may use that value in the other questions. (I think it&';s question 7).
Answers should be on the next slide.
Enjoy
