Homework Help: Gauss-Jordan Elimination

  1. Mar 25, 2009 #1
    1. The problem statement, all variables and given/known data

    How would I solve this using Gauss-Jordan Elimination?

    x - 2y + 3z = 0
    x + y - z = 4
    2x - 4y + 6z = 5

    which I think becomes:

    1 -2 3 | 0
    1 -1 -1 | 4
    2 -4 6 | 5

    But I'm confused as to the process to achieve the answer. :S

    You have a mistake in the middle row. It should be 1 1 -1 4. As for solving the system, I assume that you have a book that describes the method of Gauss-Jordan elimination (if not, Wikipedia has an article, as always). It's straight-foward and mechanical, no tricks.
