Question 1159209
let a = A's age now
let f = F's age now
:
Write an equation for each statement, simplify 
:
Five years ago, Ahmet was three years older than twice Fatih's age.\
a - 5 = 2(f-5) + 3
a - 5 = 2f - 10 + 3
a - 5 = 2f - 7
a = 2f - 7 + 5
a = 2f - 2
In seven years Ahmet's age will be 9 less than two times Fatih's age.
a + 7 = 2(f+7) - 9
a + 7 = 2f + 14 - 9
a + 7 = 2f + 5
a = 2f + 5 - 7
a = 2f - 2
As you can see, we got exactly the same equation for each statement.
There are numerous solutions, from F being 6 to F being 51 when A will be 100. no wonder you are having difficulty, 
this is a bad problem.



How old are Ahmet and Fatih?
