    Word Problem -- thanks for looking/helping!

    Here's a word problem I want verification that I'm "getting it"
    Let me know the steps involved

    In 24 years, Herbert's age in years will be twice Jack's age in years.
    is A>B B>A or A=B?
    A: Jack's age now if Herbert is 34
    B: 10

    Here's what I was thinking:
    Is the algebra herbert’s age in 24 yrs equals twice jacks age in 24 years?
    H + 24 = 2 (J + 24) which incidentally turns out to be
    H + 24 = 2J herberts age in 24 years is twice jacks age (now) weird!

    If J was 10, then herberts age would be negative… by this eqn.
    And if H = 34, then J = 29.

    I donno, what do you think ?

    There is a mistake here: you should get H=2J+24

    If, in 24 years, Herbert's age will be twice Jack's age, then

     H + 24 = 2(J + 24).

    But this gives  H + 24 = 2J + 48 .

    P.S. Sorry for the edits... badgerigar made me doubt my logic...

    Badgeriger,
    yes I made a typo, i meant to write what you did.

    Quote: "There is a mistake here: you should get H=2J+24"
    (i don't see anywhere to type in a quote box...)

    H + 24 = 2 (J + 24)
    H=2J + 24

    Prove It, you said:
    "But this gives ."

    So you are agreeing to the layout of this problem that I thought of?
    cool,
    thanks
