Question

1 The cost of the book is 5 rupees more than twice the cost of a pen. Show this using linear equation by taking Cost of book(x) and cost of a pen(y). ​

Answer 1

Let the cost of books be : Rs. x

Let the cost of pen be: Rs y

Given : Cost of book is Rs 5 more than twice the cost of pen

Henceforth the required linear equation is :

                                x=2y+5

Answer 2

Answer:

x= 2y + 5

Step-by-step explanation:

Cost of 1 book = x

cost of 1 pen = y

therefore... Equation will be

x= 2y+5
