Algebra 60 - Parametric Equations with Gauss-Jordan Elimination

The lecture explains how to identify and describe infinite solution sets using parametric equations. It covers the process of transforming a system of equations into reduced row echelon form to determine if it has unique, no, or infinite solutions. The lecture also provides examples of systems with different numbers of free variables and discusses the graphical representation of solution sets as subspaces in higher-dimensional spaces.
