Figure 2: Graphical Solutions |

| Graphs provide a valuable resource for solving simultaneous equations. Instead of solving two related equations mathematically, it is often possible to graph the two equations to find their point of intersection. This graph reveals that when x=2 and y=6, the equations y=3x and y=x+4 intersect. Therefore, (2,6) is the solution to these equations. | ||||||
