Algebra 55 - Gauss-jordan Elimination

The video tutorial by Professor Von Schmohawk at Why U explains how to represent a system of linear equations using an augmented matrix. It covers the process of Gaussian elimination to reduce matrices to row echelon form and further simplifies them to reduced row echelon form using Gauss-Jordan elimination. The tutorial highlights the properties and uniqueness of reduced row echelon form, demonstrating how solutions can be directly read from the matrix. The video also discusses the use of elementary row operations and the implications of matrix transformations on the system of equations.
