What am I doing wrong I am using the Gauss Jordan method to calculate this answer and some other students are coming up with differant answers.
Problem is
3x+y+z=5,
x+5y-z=-8,
10x+7y+z=2
My answer is (-6z+3,7z-4
_________, z
( 11 11)
Where I have +3 they have +33 and where I have -4 they have -44 Can you let me know how they came up with the larger numbers

This does not make sense to me. You have three equations, three unknowns. YOu can solve for x,y,z. Whatever you are doing, I don't understand.

Answers are
1-(-6z+3/11, 7z-4/11,z)
2-(-6z+33/11,7z-44/11)
I got #1 for my answer and some got #2 which one is right. Some got all kinds of numbers.

well, I didn't get anything like that, I got a specific number solution for x, y, and z.
When you say "calculate" and answer, that to me implies looking for a specific solution.
Here is a Gauss Jordan applet, check your work

My mistake New at this Question should be Use the Gauss-Jordn method to solve the system of equations.
well, both your 1) and 2) are NOT solutions. Solutions have specific values for x,y, and z.
