Hi guys, today I will b showing you what we have been doing in math, well we are in quarantine.
What we have been learning about is a bit of substitution and how it works. What we have is, we learnt all about what it is and how to do it and then we had to figure out fifteen answers for the questions we have been given. With that we also had to show how we worked it out, in a book or on the slide, we just had to show how we did it.
This is my slid and a picture of how I did it and my answers.
Do you know how to do substitution?
