Answer 2

Answer: Hi here is your ans

Ans - Let the cost of a notebook = Rs x            The cost of a pen = y            According to the condition, we have                            [Cost of a notebook] = 2 × [Cost of a pen]            i.e.            [x] = 2 × [Y]            or              x = 2y            or              x – 2y = 0       Thus, the required linear equation is × – 2y = 0
