Question 1033069
Ashley is 10 years older than Brandon. In seven years, Ashley will be twice as old as Brandon. How old are they? 
------
A = B + 10
A+7 = 2(B+7)
------
Substitute for "A" and solve for "B"::
B+10 + 7 = 2B + 14
-----
B = 17-14 = 3 (Brandon's age now)
----
A = B + 10 = 13 (Ashley's age now)
