How to solve system of equations with 3 variables

This type of equation creates a line where each point on the line represents an (x, y) ordered pair that is a solution to the equation. When you have 2 equations with the same 2 variables, then you have a system of linear equations. The solution to the system is the point (or points) that the 2 linear equations have in common. Hope this helps.
