Question

the cost of a notebook is trice the cost of pen.( if pen cost x and notebook is y) write a linear equation in two variables to represent this statement is​

Answer 1

Answer:

the required linear equation is

Y= 3X

Answer 2

${\large\red{\sf{\underline{ Solution:-}}}}$

• Let the cost of a notebook to be = ₹ x

• Let the cost of a pen to be = ₹ y

$\sf\red{According\:to\:the\:question,}$

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

i.e., Cost of a notebook = 2×Cost of a pen

$→x = 2y$

$→x - 2y = 0$

x-2y = 0 is the linear equation in two variables yo represent the statement 'The cost of a notebook is twice the cost of a pen'.
