Unformatted text preview: Sure enough x = -3 and y = 1 is a solution.
So, since there are an infinite number of possible t’s there must be an infinite number of
solutions to this system and they are given by, x=t
y=- t55 where t is any real number Systems such as those in the previous examples are called dependent.
We’ve now seen all three possibilities for the solution to a system of equations. A system of
equation will have either no solution, exactly one solution or infinitely many solutions. © 2007 Paul Dawkins 323 http://tutorial.math.lamar.edu/terms.aspx College Algebra Linear Systems with Three Variables
This is going to be a fairly short section in the sense that it’s really only going to consist of a
single example to illustrate how to take the methods from the previous section and use them to
solve a linear system with three equations and three variables. As we will see these can be fairly
involved problems and there is a third solution technique that is often easier to use on these types
of systems. We will b...
