Question

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

Answer 1

Answer: 2x - y =0

Step-by-step explanation:

consider price of pen = x

and price of book = y

according to statement

y = 2x

or

2x -y = 0

Answer 2

Lets assume cost of pen as x and cost of notebook as y

2x=y

Because we have to make both equal so coefficient 2 will be written with x
