Question

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

Answer 1

Step-by-step explanation:

Let cost of book = ₹x

Let cost of pencil = ₹y

A.T.Q. x+y = 3y

Answer 2

Answer:

the liniar equation can be like this:-

let the coast of pencil -x

so book coast would be-y

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

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

Then x=2y

or, x−2y=0.

This is the required linear equation in two variable.,,,,,

u can do like this alsooo-----

-Given that cost of a notebook (x) is twice the cost of a pen(y). So, x = 2y. x – 2y = 0 is the linear equation in two variables that represent the statement.
