Algebra 54 - Gaussian Elimination

The video tutorial by Professor Von Schmohawk at WHY U covers the use of augmented matrices to represent systems of linear equations. It introduces Gaussian elimination, a method to simplify matrices to row echelon form, making it easier to solve the corresponding system of equations. The tutorial explains the requirements for a matrix to be in row echelon form and demonstrates the process of Gaussian elimination, including the use of elementary row operations like swap, scale, and pivot. It also covers back substitution, a method to solve the simplified system of equations. The video concludes with a review and a brief mention of Gauss-Jordan elimination.
