Question 35197: Use Gaussian Elimination to reduce the augmented matrix for the following system of linear
equations to upper triangular form, and use back-substitution to solve the system.
x + y − z = 3; (1)
−x + 2y + z = 0; (2)
2x − y − z = 1. (3)
The book gives the answer but not how to get the answer. Please i need to understand what they mean. Answer by stanbon(75887) (Show Source):
You can put this solution on YOUR website! Use Google with the search stream
"Math World Gaussian Elimination" to
see a nice example of what you need
to do with this system of three
equations in three unknowns.
