If this were the reduced row echelon form of an augmented matrix,(adsbygoogle = window.adsbygoogle || []).push({});

1 2 0 1 1 0 3

0 0 1 2 1 0 1

0 0 0 0 0 1 2

0 0 0 0 0 0 0

What is the form of the following answer given, and how can I understand it?

(x1; x2; x3; x4; x5; x6) = (3; 0; 1; 0; 0; 2)+ t(1; 0; 1; 0; 1; 0)+ s(1; 0; 2; 1; 0; 0)+ u(2; 1; 0; 0; 0; 0)

for s; t; u [itex]\in[/itex] ℝ.
