Have you woken up recently wondering how to solve simultaneous equations with more than two variables? I know I haven't! This video, however, is my take on how to solve these pesky equations. I show you how to use your CAS to solve them in the simplest way before moving on to showing you how to do it using pencil and paper. The last section of this video looks at the idea of parameters and how to use them to find solutions where planes meet in a straight line.
