Gaussian Elimination applied to square linear system Ax = b is the systematic use of row operations on the augmented matrix [A | b] to obtain an equivalent linear system [U|c] where matrix U is in upper triangular and then apply back substitution to the upper triangular system to solve Ux = c for x. It is usually understood as a sequence of operations performed on the corresponding matrix of coefficients. Jordan-Gauss elimination is convergent, meaning that however you proceed the normal form is unique. The unique solution is x, =x2 =, and x3O A(Simplify your answers. Again, we are transforming the coefficient matrix into another matrix that is much easier to solve, and the system represented by the new augmented matrix has the same solution set as the original system of linear equations. Here is an extension of Gauss' method that has some advantages. Solve the linear system by using the Gauss-Jordan elimination method. If we were to do a system of four equations (which we aren't going to do) at that point Gauss-Jordan elimination would be less work in all likelihood that if we solved directly. x - y - z = 4 2x - 2y - 2z = 8 5x - 5y - 5z = 20. The advantage of using matrices to solve systems of linear equations is that it is a procedural and rule-based process.
