    80 and 85

    Step-by-step explanation:

    Let a and b be those numbers

    a*b = 6800

    a - b = 5

    Use the substitution method.

    a = 5 + b

    (5 + b) * b = 6800

    5b + b*b = 6800

    bb + 5b - 6800 = 0

    b = - 5/2 + root (25 - 4*1 * (-6800)) / 2

    b = - 5/2 + 165/2

    b = 80

    or b = - 85

    a - b = 5

    a - 80 = 5

    a = 85
