    Let the two numbers be x and y.

    Given,

    x + y = 23

    x = 23 - y

    Also given,

    y = 2x - 1

    y = 2 (23 - y) - 1

    y = 46 - 2y - 1

    3y = 45

    y = 15

    x = 23 - y = 23 - 15 = 8

    Hence, the two numbers are 15 and 8.

    x + y = 23

    x = 2y-1

    y + 2y-1 = 23

    3y-1 = 23

    3y = 24

    y = 24/3 = 8

    y = 8

    x = 2*8-1 = 15

    15+8 = 23

    the 2 numbers are 8 & 15
