Solution:

Given,

……. (i)

……. (ii)

For equation (i),

When , we have

When , we have

Thus we have the following table giving points on the line 

x
y

For equation (ii),

We solve for y:

So, when

And, when

Thus we have the following table giving points on the line 

x
y

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

Clearly the two lines intersect at a single point

Hence, and
