Solve each of the following systems of equations graphically:

2x – 3y + 13 = 0


3x – 2y + 12 = 0.

We can rewrite the equations as:


2x – 3y = - 13


& 3x – 2y = - 12


For equation, 2x – 3y = - 13


First, take x = 0 and find the value of y.


Then, take y = 0 and find the value of x.


x



0



- 13/2



y



13/3



0



Now similarly solve for equation, 3x – 2y = - 12


x



0



- 4



y



6



0



Plot the values in a graph and find the intersecting point for the solution.



Hence, the solution so obtained from the graph is ( - 2,3), which is the intersecting point of the two lines.
