consider the systems of linear equations given via the (combined) augmented matrix

(-12, -6, -13, 84, 0, 0, -1, 0

-2, 0, -2, 13, 0, 0, 0, 1

1, 0, 1, -6, -4, 0, 0, 0

26, 13, 28, -181, 0, 4, 0, 0)

which can be reduced to the Echelon form

(1, 0, 0, 0, -4, 24, -13, 0

0, 1, 0, 0, -0, 4, -2, 1

0, 0, 1, 0, -48, -24, 13, 6

0, 0, 0, 1, -8, 0, -0, 1)

I wasn't able to parse your question, but the HE.NET team is hard at work making me smarter.
