Systems of Equations and Inequalities

What is a system of equations?  It is a collection of two or more equations with the same solution (common point) to both equations. The solution to a system of equations is the common solution (common point) to both equations. 

When do we use a system of equations?  Typically, it used when there is more than one unknown quantity and you want a specific amount for each quantity.
