Gaussian elimination is often used as a pen-and-paper exercise for solving simple linear systems, but the geometric counterpart may remain elusive during this exercise. Use this Demonstration to visualize the planes and solutions of a system of three linear equations as you apply elementary row operations to the system. Alternatively, simply play around with the parameters to visualize various types of solutions.
