Algebra 57 - Dependent Equations and Systems

The video tutorial introduces systems of linear equations, focusing on dependent and independent systems. It explains how independent systems have unique solutions or no solutions, while dependent systems can have infinitely many solutions. The concept of linear combinations is introduced to identify dependent systems, even when equations are not multiples of each other. Examples demonstrate how dependent systems can have unique, infinite, or no solutions. The tutorial concludes with methods to identify dependent systems using Gauss-Jordan elimination.
