Solve the following equations using graphical method:

Given,

……. (i)

……. (ii)

From equation (i),

⇒

When , we have

When , we have

Thus, we have the following table giving Points on the line

a              

b               

From equation (ii),

Solve for b:

⇒

So, when

And, when

⇒

Thus, we have the following table giving Points on the line

a               

b               

Graph of the equations (i) and (ii) is given below:

From given graph, we can see that, the two lines intersect at a single Point say P

Hence, and .
