Question

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

Answer 1

Answer: Let the cost of the notebook be equal to X and cost of pen be equal to Y.

Therefore,            x = 2y

                           x - 2y = 0

Hence, x - 2y = 0 is the linear equation in two variables

Hope this helps!!

Answer 2

Answer:

Step-by-step explanation:

Let the cost of pen is rs.x

Let the cost of notebook is rs.y

ATQ

Y=2x

2x-y= 0
