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