    Ages of Dan and Cary are 29 and 33 respectively.

    Step-by-step explanation:

    Step 1:

    Form equations out of the given details. Let the age of Dan be x, then age of Cary is x + 4.

    In 7 years, sum of their ages = 76

    ⇒ (x + 7) + (x + 4 + 7) = 76

    ⇒ 2x + 18 = 76

    ⇒ 2x = 58

    ⇒ x = 29

    Step 2:

    Calculate age of Cary.

    ⇒ x + 4 = 33
