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

Given:

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

To do:

We have to write a linear equation in two variables to represent the given statement.

Solution:

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

According to the question,

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

This implies,

$x = 2\times{y}$

$x = 2y$

$x-2y=0$

Therefore,

The linear equation in two variables to represent the given statement is $x-2y=0$.
