The videos for linear equations and relations are almost complete but it wouldn't be complete without showing practical examples of how to apply the solving of simultaneous equations. Hence, welcome to this video on practical applications of simultaneous equations. It doesn't get any more exciting than this. I look at three examples and show you how to extract the two equations you need, and then solve them by hand and checking with the CAS. I fully explain the questions in an easy to understand way and hope you have some fun whilst learning.
