I'll say:
A's age =
B's age =
------------------
I will also say that the problem starts
off talking about A
-------------
" When I had the age you have " means
when A's age =
----------------------
How old was B then?
The difference in their ages never changes, so
B was
-----------------------------
it says A is presently twice that age, so
(1)
---------------------
" and when you'll be my age " means B's
age =
At that time, A's age will be
---------------------
The sum of these ages is:
(2)
----------------------
(1) and (2) have 2 unknowns, so it's solvable
(1)
(1)
(1)
(1)
--------------------
(2)
(2)
Substitute (1) into (2)
(2)
(2)
(2)
(2)
and, since
(1)
(1)
(1)
-----------------
A is 32
B is 24
---------
check:
" when i had the age you have "
( When A was 24 )
How old was B then?
B was
------------------
A is twice that age, or
correct
------------
When B will be 32, and A will be
, the sum
of their age will be 72
correct again
-------------
Hope it's not confusing
