Systems of Equations

The method of Gaussian Elimination is a systematic version
of the process of eliminating variables by adding and subtracting multiples
of the given equations. To save space the process is often written
in terms of just the array or 'matrix' of numerical coefficients.
Here are a couple of discussions of the issue at Hofstra University:

this
is for a system with 2 unknowns , and this
is for 3.

Here is another
one at Oregon State,

and this review
of systems of linear equations is part of a site at BCIT devoted to
applications of mathematics in technology.

For further study of systems of linear equations and related topics
you may want to look at a course in Linear
Algebra (eg Langara's Math
362)

You might also check our 'raw list' (of links provided without comment)
to see if there are any more
examples there that we haven't yet included here.

If you have come across any good web-based illustrations of these and
related concepts,

please do let
us know and we will add them here.
