Q10 of 44 Page 3

Solve each of the following systems of equations graphically:

3x + 2y = 4,


2x – 3y = 7. (CBSE 2006)

For equation, 3x + 2y = 4


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



x

0

4/3

y

2

0

Now similarly solve for equation, 2x - 3y = 7



x

0

7/2

y

- 7/3

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, - 1), which is the intersecting point of the two lines.
