SFU MATH 232 2.2 Solving Linear Systems by Row Reduction

SFU Math 232 Section 2.2. This is the main lecture for section 2.2. This lecture explains what a row echelon and a reduced row echelon matrix look like and shows how you find the solution to the corresponding system of linear equations from either of these two forms. Then Gaussian elimation is used to take any matrix and put it into row echelon form and Gauss-Jordan elimination is used to further reduce to reduced row echelon form. The main point of this is that there is a fully algorithmic way to take any augmented matrix representing a system of linear equations and reduced to a form (reduced row echelon form) from which the solution to the corresponding system of linear equations can simply be read off.
