Twice = 2 times

Let age of son be x years.
Age of father's be y years
Now according to ques.
x+y=48
Y=2x
So eq.becomes,
x+y=48
2x-y=0
Adding these eq.
3x=48
x=16
y=2x =2×16=32
Age of son is 16
Age of father is 32.

.
Let the son's age is x years.

Then the father's age is 3x years,  (twice older means "three times old as") and the condition says that

x + 3x = 48.


Hence,  4x = 48  and x =  = 12.


Answer.  The son is 12 years old.  The father is 36 years old.
