NOTE: This is not a homework question, rather it's a question I made up to practice using Row-Echelon. I know how to solve it easily using elimination or substitution, and by using Cramer's Rule (but my instructor suggests I rather not since it's too much work :P) The solutions are x = -1, y= 5, and z= 2
3x -y + 2z = -4
-4x +y -5z = -1
x +4y -z = 9
Can anyone give me an example of how to solve it using Row-Echelon Form?
The Attempt at a Solution
I'm sorry! I'd try it myself, but I don't understand it at all, and I can't seem to study it without a textbook. Again, I know how to solve it easily by using Elimination and Substitution.
