In this tutorial, we solve simultaneous systems of linear equations.We first look at the substitution method for solving a system of linear equations with 2 variables, and see that there can be a unique solution, or infinitely many solutions, or even no solution. Finally, we look at the general method of Gaussian Elimination that can be used to solve any system of simultaneous linear equations.* Aimed at students in their final two years of high school.* Studying mathematics is best done by working through examples and exercises. There are many interactive examples and exercises in this tutorial that must be completed to achieve 100% progress.* Written by a Maths teacher with 20 years of teaching experience.* Completely free (no Ads).* Works without internet so that you can learn Algebra while travelling in the train, bus etc. Internet only required for links to privacy policy and other tutorials. * Made with GameMaker (www.yoyogames.com)* Only a 14 MB download.
