    9 and 14

    Step-by-step explanation:

    One number is 5 less than a second number.

    a = b - 5

    :

    Twice the second number is 8 less than 4 times the first.

    2b = 4a - 8

    replace a with (b-5)

    2b = 4 (b-5) - 8

    2b = 4b - 20 - 8

    2b - 4b = - 28

    -2b = - 28

    b = 14

    then

    a = 9
