Inverse of a 3 by 3 Matrix Using Gauss-Jordan Method

This video goes through the steps in finding the inverse of a 3 by 3 matrix. There are three objectives 1 - Explain what is a matrix in reduced row echelon form (rref) 2- Write the augmented matrix of the equation to solve 3 - Use the basic row elementary operations to rewrite the augmented matrix in reduced row echelon form 4 - Read the inverse matrix All the detailed steps are explained in the videos starting from the augmented matrix to reading the final answer which is the inverse matrix.
