Gauss-Jordan Elimination and RREF - Unique Solution

* Look below for timecodes for easier navigation through the video.
In this video, we will solve a system of three equations in three variables using Gauss-Jordan elimination. We will also learn how to set up the augmented matrix for a system and how to reduce it to the row-echelon form (REF) and reduced row echelon form (RREF).
This system has a unique solution.

00:00 Constructing the augmented matrix
01:11 Carrying it to the row echelon form (REF)
04:04 Carrying it from REF to the reduced row echelon form (RREF)
