Applying Gauss's Method to any matrix always yields Echelon Form.

Gauss's Method: If a linear system is changed to another by one of these operations

  1. an equation is swapped with another
  2. an equation has both sides multiplied by a nonzero constant
  3. an equation is replaced by the sum of itself and a multiple of another

then the two systems have the same set of solutions.

Solution sets look something like:

x y z
1 0 0
-1/3 2/3 1 z
