Solve each of the following systems of equations graphically:

3x + 2y = 12


5x – 2y = 4. (CBSE 2006)

For equation, 3x + 2y = 12


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


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

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.
