Lesson Summary:

In this lesson, we learn how to use matrix operations to solve the matrix equation with a graphing calculator. The matrix equation involves a square matrix of coefficients multiplied by a column of unknowns, equaling a column of constants or outputs. By multiplying both sides of the equation by the inverse of the coefficient matrix, we can find the values of the unknowns. The process is demonstrated step-by-step using a graphing calculator, showing how to enter the matrices and compute the solution.
