Solving Systems of Linear Equations

This video tutorial demonstrates how to solve a system of linear equations using an augmented matrix and the TI-84 calculator. It covers converting equations to standard form, forming the augmented matrix, entering it into the calculator, and using the reduced row echelon form to find the solution. The video concludes with interpreting the solution and classifying the system as consistent and independent.
