    Answer:

    Step-by-step explanation:

    “The difference of two numbers is 15.”

    x-y = 15

    x>y

    “Five times the smaller number is the same as 9 less than twice the larger number.”

    5y = 2x-9

    y = x-15

    substitution

    5(x-15) = 2x-9

    5x-75 = 2x-9

    3x = 66

    x = 22

    y = x-15 = 7
