Consider the following Gaussian-elimination-Gauss-Jordan hybrid method for solving the system (6.4). First, apply the Gaussian-elimination technique to reduce the system to triangular form. Then use the nth equation to eliminate the coefficients of xn in each of the first n-1 rows. After this is completed use the (n-1) st equation to eliminate the coefficients of xn-1 in the first n-2 rows, etc. The system will eventually appear as the reduced system in Exercise 12 . a. Show that this method req
