Solving Systems of Equations. In order to solve for two variables, you need to have two equations. If you only have one equation there are an infinite amount of ordered pairs (x,y) that will work. For example: 4x – 2y = 16 you can have x = 4 and y = 0 (4,0) and (2, -2) and (0, -4) and an infinite amount of others.
