Question

3) 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

Step-by-step explanation:

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

Given the cost of a notebook is 5 Rs more than twice the cost of a pen.

Then x=2y+5

or, x−2y-5=0.

This is the required linear equation in two variable.
