The cost of a notebook is twice the cost of a pen. Write a linear equation in twovariables to represent the statement. About the author Sadie
Let the cost of a notebook to be = ₹ x Let the cost of a pen to be = ₹ y 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 [tex] \: \: \: \: \: \: : \sf \ \implies x = 2×y [/tex] [tex] \: \: \: \: \: \: \sf : \implies{x = 2y}[/tex] [tex] \: \: \: \: \: \: \ : \implies \boxed {\frak{x – 2y = 0} } \pink\bigstar[/tex] Hence, x-2y = 0 is the linear equation in two variables to represent the statement ‘The cost of a notebook is twice the cost of a pen’. тнαηк үσυ @itzshivani Reply
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
[tex] \: \: \: \: \: \: : \sf \ \implies x = 2×y [/tex]
[tex] \: \: \: \: \: \: \sf : \implies{x = 2y}[/tex]
[tex] \: \: \: \: \: \: \ : \implies \boxed {\frak{x – 2y = 0} } \pink\bigstar[/tex]
Hence,
