In previous videos I have looked at how to solve simultaneous equations using substitution, elimination and graphically. These are all pretty involved - which is why it's awesome that you can solve simultaneous equations using Matrices. Having spent some time looking at matrices, this video is going to make life much, much easier! The video is part of the Year 11 General Maths Units 1 and 2 course for VCE. The video has a number of worked examples where I explain the theory to ensure that you understand how to do this awesome method of solving simultaneous equations!
