Solving Systems of Equations by Linear Combination

This video tutorial teaches how to solve systems of equations using linear combination, also known as elimination. It begins with an introduction to the method, followed by a graphical approximation of the solution. The tutorial then provides a detailed algebraic solution using linear combination, emphasizing the simplicity of this method compared to substitution, especially when dealing with coefficients. The video concludes by verifying the solution through graphing and algebraic methods.
