I always found that these are easy when the information is restated in different cases
present:
son's age  x
man' age  3x
in 11 years from now:
son's age = x+11
man's age = 3x+11
it said, at that time the man is twice as old as his son
3x+11 = 2(x+11)
3x + 11 = 2x + 22
x = 11
The son is now 11, and the man is now 33
check:
now son is 11, man is 33
in 11 years:
son is 22 , man is 44
is the man twice as old as his son at that time ?
YES.
