About the method. To calculate inverse matrix you need to do the following steps. Set the matrix (must be square) and append the identity matrix of the same dimension to it. Reduce the left matrix to row echelon form using elementary row operations for the whole matrix (including the right one). This method is a classical one, which is called Gaussian elimination. That is a way of elimination of variables named after Gauss, who was the famous mathematician of the world about 200 years ago. Let us consider an example of elimination of variables in a linear system. Consider a system of two linear equations in three variables.
