In this section, we learn about systems of linear equations in two variables. A system of linear equations consists of two or more linear equations with the same variables. Suppose we saw: 2x - 5y = 10 and 3x + 7y = 14, these two equations would make up a system of linear equations. When we obtain a solution for such a system, we are looking for an ordered pair that satisfies both equations of the system. There are a few methods that we can employ to find our answer, in this section we focus on graphing. To use the graphing method, we simply graph each line of the system and look for the point of intersection. This point of intersection is the solution to the system, since it satisfies both equations of the system.
