Answer 1

1. The cost of a notebook is twice the cost of a pen. Write a linear equation in

variables to represent this statement

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

Answer if the costof notebook is x then pen cost is 2x

Answer 2

Let the cost of a notebook to be = ₹ x

Let the cost of a pen to be = ₹ y

According to the question,

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

i.e., Cost of a notebook = 2×Cost of a pen

$→x = 2y$

$→x - 2y = 0$

x-2y = 0 is the linear equation in two variables yo represent the statement 'The cost of a notebook is twice the cost of a pen'.
