Homework Help: Linear Algebra

Posted by Robert on Friday, September 21, 2012 at 9:56am.

Solve the following system using Gauss's algorithm

(a)
x1 + 2x2 + 4x3 + 6x4 = 3
2x1 + x2 + 3x3 = -6
-2x1 + x2 + 6x3 + 4x4 = -11
2x1 + x2 + x3 = 0

so the matrix will be:

1 2 4 6 3
2 1 3 0 -6
-2 1 6 4 -11
2 1 1 0 0
