samantha has an older brother right now he is twice her age but 8 years ago her brother was 3 times her age how old is each person now
----------
Equations:
b = 2s
b-8 = 3(s-8)
----
Substitute for "b" and solve for "s"::
2s - 8 = 3s-24
-----
s = 16 (samantha's age now)
-----
Solve for the brother's age::
b = 2s = 32 yrs (Brother's age now)
