Gauss-Jordan Elimination process

[Guest]

4x1 + 5x2 + 2x3 = 11
2x2 + 3x3 - 4x4 = -2
2x1 + x2 + 3x4 = 12
x1 + x3 + x4 = 9

Using a Gauss-Jordan Elimination process, x3 =

I really don't know how to do this elimination process. Can someone help me on this one?

I'm sorry, but we can't teach classes here, so I'm afraid we can't teach you how to do Gaussian or Gauss-Jordan elimination.

For online lessons, try a search engine. For instance, Google provides about a half-million results for keywords "system solve gauss" (without the quote-marks).
