Algebra Tutorial 18

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.
