Each equation represents a line on a graph (for 2 dimensions). The solution you are searching for is the intersection of the lines. There are three possible outcomes: 1) The lines intersect and the corresponding x,y coordinates are the solution to the system of equations. 2) The lines are parallel and the system is what we call inconsistent meaning there is no solution. 3) Lastly the equations could represent the exact same line, which means that they intersect everywhere and the solution is the entire line.
