The cost of a notebook is twice the cost of a pen. Write a linear equation in two variables to represent this statement.

(Take the cost of a notebook to be Rs x and that of a pen to be Rs. y)


Let the cost of pen be y and the cost of notebook be x

As per the question,


Cost of a notebook = Twice the cost of pen = 2y


So,


2y = x


x – 2y = 0


This is a linear equation in two variables to represent this statement
