    let the two number be x and y

    So according to the question ,

    x+ y = 5______¡

    or, 9(x- y ) = 9

    or, x- y = 1______¡¡

    From ____¡ and _____¡¡

    x + y = 5

    + x – y = 1

    _____________

    then , keeping the value of x in _______¡

    x+ y = 5

    or, 3 + y = 5

    or, y = 5-3
