The systems of equns.has no solution.

#### Explanation:

Here,

Dividing each term by

Also given that,

Dividing each term by

Subtracting equn.

**Thus, the pair of equn. has no solution.**

Let us draw the graphs of equn.

From the graph ,we can say that the lines are parallel.

i.e.two lines donot intersect anywhere.

**So, the systems of equns.has no solution.**

Note:

We know that :If for

In short,
