Q. 7

# Solve each of the following systems of equations graphically:

2x + 3y + 5 = 0,

3x + 2y – 12 = 0

Answer :

We can rewrite the equations as:

2x + 3y = - 5

& 3x + 2y = 12

For equation, 2x + 3y = - 5

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

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

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

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.
