Homework Statement
x1 + 2x2 = 9 ,
6x1 + 6x2 -8x3 = 1 ,
-3x2 +x3 = 0 [/B]
Here's a question from my book . I'm asked to find the x1 , x2 and x3 by using the gaussian elimination with pivoting .
Homework Equations
The Attempt at a Solution
Pls refer to this thread for the lecturer's method
https://www.physicsforums.com/threads/gaussian-elimination-pivoting.905132/#post-5699372[/B]
By using the lecturer's method ( circle out the max element in each column ) , I found that all the greatest element lies in 6x1+ 6x2 - 8x3 = 1 ...
So , how could all the largest element lies in the same row ?
