    X + y = 1 ... x = 1 - y

    x * y = 0.09

    y (1 - y) = 0.09

    y - y^2 = 0.09 ... re-arrange

    y^2 - y + 0.09 = 0

    (y - 0.9) (y - 0.1) = 0

    y - 0.9 = 0 x + y = 1

    y = 0.9 x + 0.9 = 1

    x = 0.1

    y - 0.1 x + y = 1

    y = 0.1 x + 0.1 = 1

    x = 0.9

    so ur 2 numbers are : 0.1 and 0.9
