Gauss elimination method with pivoting
WebSolve the following system of equations using Gaussian elimination. –3 x + 2 y – 6 z = 6. 5 x + 7 y – 5 z = 6. x + 4 y – 2 z = 8. No equation is solved for a variable, so I'll have to do the multiplication-and-addition thing to simplify this system. In order to keep track of my work, I'll write down each step as I go. Webpivoting and then with pivoting. 1.4.1 The Algorithm. We illustrate this method by means of an example. Example 1. 4x 1 - 2x 2 + x 3 = 15 (1) - 3x 1 - x 2 + 4x 3 = 8 or x 1 - x 2 + …
