Travis is 24 years older than his sister Danielle.
In 13 years, he will be twice as old as Danielle.
How old is each of them now?
----------
T = D + 24
T+13 = 2(D+13)
---------------------
Substitute for "T" and solve for "D"::
D+24 + 13 = 2D + 26
--------------------
D = 11 (Danielle's age now)
T = D+24 = 35 (Travis' age now)
