Systems of equations

A system of equations is a set of two or more equations that you deal with at one time. When solving the system, you must consider all of the equations involved and find a solution that satisfies all of the equations. When you graph a system, the point of interesection is the solution. A linear system of equations will only have one solution, and that is the point of intersection. Although, as always, there are times when you will find no solution or an infinte number of solutions. When a linear system has no solution, then the lines are parallel. If a linear system has an infinite amount of solutions, then the lines are the same.
