The Reduced Row Echelon Form of a Matrix Is Unique: A Simple Proof

We will solve systems of linear equations algebraically using the elimination method. In other words, we will combine the equations in various ways to try to eliminate as many variables as possible from each equation. There are three valid operations we can perform on our system of equations:. We can make our life easier by extracting only the numbers, and putting them in a box:. This is called an augmented matrix.
