A system is a pair of linear equations that have the same x and y values (a point in common on a graph)
You can try to figure it out in your head, or you can graph the equations and use sick visuals to find the solution.
In this graph, we have a system for lines x + 4 = y and 4x + 10 = y. When you take a look at the lines, they seem to intersect at a specific point. This point is (-2,2) and is the solution to the equation
In the graph, we have some really ugly points and for this equation, using a graph is helpful for understanding systems, but don’t rely on it because it takes too long and sometimes it not very accurate.
