    The first number is 5, and the other number is 12

    Step-by-step explanation:

    1st Number = n

    2nd number = 2n + 2

    1st Number * 2nd Number = 60

    n (2n+2) = 60

    2n^2 + 2n = 60

    2n^2 + 2n - 60 = 0

    Factor Out:

    2 (n-5) (n+6) = 0

    n-5 = 0 n+6 = 0

    n = 5 n = - 6

    n = - 6 wont make sense so n = 5 would be the answer

    Check:

    5 (10+2) = 60

    5 (12) = 60

    60 = 60
