Unformatted text preview: n three dimensional space and solution to this system is the
one point that all three of the planes have in common.
Note as well that it is completely possible to have no solutions to these systems or infinitely many
systems as we saw in the previous section with systems of two equations. We will look at these
cases once we have the next method out of the way. © 2007 Paul Dawkins 325 http://tutorial.math.lamar.edu/terms.aspx College Algebra Augmented Matrices
In this section we need to take a look at the third method for solving systems of equations. For
systems of two equations it is probably a little more complicated than the methods we looked at
in the first section. However, for systems with more equations it is probably easier than using the
method we saw in the previous section.
Before we get into the method we first need to get some definitions out of the way.
An augmented matrix for a system of equations is a matrix of numbers in which each row
represents the constants from one equation (both the coefficients and the constant on the other
side of the equal sign) and each column represents all t...
