Augmented Matrices and Row Echelon Form

This video tutorial explains how to transform an augmented matrix into row echelon form to solve systems of equations. It covers the definition of row echelon form, the process of Gaussian elimination, and provides examples of solving both 2x2 and 3x3 systems. The video concludes with a brief introduction to reduced row echelon form.
