    • 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

     \:  \:  \:  \:  \:   \:  : \sf  \ \implies  x = 2×y

     \:  \:  \: \:  \:  \:   \sf   : \implies{x = 2y}

     \:  \:  \: \:  \:  \:   \   : \implies \boxed {\frak{x  -  2y = 0} } \orange\bigstar

    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’.

    Answer:

    let cost of notes be y

    let cost a pen be x

    cost of note= 2x=y

    x=y/2

    2(y/2)=y

    2y/4=y

    pls mark as BRAINLIEST I will follow and thank you
