Ben is 12 years older than Lisa.
The sum of their ages is 64.
How old is Ben?
---------------------------
B = L + 12
B + L = 64
-----------------------
Substitute for "B" and solve for "L"::
L + 12 + L = 64
------
2L = 52
------
L = 26 yrs (Lisa's age)
B = L+12 = 38 yrs (Ben's age)
========================
