Question

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

Answer 1

Answer:

x=2×y

Step-by-step explanation:

Note book cost = 2×cost of pen

cost of pen according to variable is y

cost of note book according to variable is x.

So, linear equation is to be x=2×y.

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'.
