matrix algebra (MATH160)

This document will have three different examples showing how to find for free variables in matrix. One of the examples will have two type of free variables and the other two examples have one. You can try solving the question I provided then check your answer with my work shown. Any question, contact me at .

In this lesson 2, you will learn how to use Gauss Jordan reduction method. There’s 3 properties that you follow to get an echelons form. Echelon form is when there’s a pivot on each row (equation). I will provide first example solving the system of linear equation using Gauss Jordan reduction method in both equations and augmented matrix form. Second example I’ll provide you a question and try to solve it yourself by looking at example 1. I will also provide the steps for example 2. Hope m...

First lesson of my matrix notes, an introduction to what is matrix and how to write it in augmented matrix by looking at a system of equation. I will be posting more lessons ASAP.
