Question

The price of a book is RS 5 more than double the price of a pen. X is value of books and Y is the value of pen .then show the linear equations in two variables.​

Answer 1

Answer:

Let the cost of a notebook be Rs. x and that of a pen be Rs. y.

Given the cost of a notebook is twice the cost of a pen.

Then x=2y

or, x−2y=0.

This is the required linear equation in two variable.
