    74, 185

    Step-by-step explanation:

    The difference in ratio units is 5-2 = 3, so each ratio unit stands for 111/3 = 37. The numbers are:

    ... 2*37 = 74

    ... 74 + 111 = 185

    2x=5y

    x-y=111

    x=111+y

    so 2x=5y is

    2 (111+y) = 5y

    222+2y=5y

    2y-5y=-222

    -3y=-222 (divide by - 3 both sides of the equation)

    y=-222 / (-3) = 74

    x=111+y = 111 + 74 = 185

    so the first number is 185 and the second is 74
