Systems of equations or simultaneous equations can also be solved by the graphical method.
To do that, we draw the graph for each of the equation and look for a point of intersection between the two graphs. The coordinates of the point of intersection would be the solution to the system of equations.
If the two graphs do not intersect - which means that they are parallel - then there is no solution.
Example :
Using the graphical method, find the solution of the systems of equations
y + x = 3
y = 4x - 2
Solution :
Draw the two lines graphically and determine the point of intersection from the graph.
From the graph, the point of intersection is (1, 2)
Have a look at the following video for another example on how to solve systems of equations using the graphical method.:
