    if you look at the question itself, we know the sum of their ages is 66 and that Devaughn is twice the age of Sydney.

    D = 2s

    66-2s=s

    3s=66

    s=22

    Sydney is 22, Devaughn is 44, equal to sum of 66

    D = devaugn's age

    s = sidney's age

    so, we know Devaugh's age is twice as Sydneys, so d = 2*s or 2s

    and we know their sum is 66

    or d + s = 66

    since d = 2s, thus

    (2s) + s = 66 < - - - solve for "s" to see Sidney's age

    what about Devaugn's? well d = 2s
