Solving Systems of Equations Using the Substitution Method
24:18This video is an instructional lecture on solving systems of equations using the substitution method. The method is particularly useful when a variable is already isolated, making it a straightforward process of substitution and algebraic operations to find points of intersection. The instructor goes through several examples, gradually increasing in difficulty, and reinforces the concepts with practical applications and demonstrations using a graphing calculator.
