Given,

……. (i)

……. (ii)

For equation (i),

⇒

When , we have

When we have

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

a
b

For equation (ii),

We 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 as below:

From graph, there is no common point between these two lines.

Hence, the given systems of equations are in-consistent.
