This is part of the QCE Year 12 syllabus for Specialist Maths. This post will introduce the system of linear equations and how to solve them. Let’s start by learning to recognise the general form of a system of linear equations in several variables and use Gaussian techniques of elimination to solve a system of linear equations.
The idea of solving linear equation using a matrix is exactly the same as using simultaneous equations, but is a faster and cleaner way to solve them! Let’s watch some videos to introduce the concepts.
