Answer:
24 and 48 
Today, the son is 24 years old, and the father is 48 years old.  
Step-by-step explanation:
(x - 10) + (2x - 10) = 52
3x + 20 = 52
3x = 72
x = 24
The father is 2 times his son's age.
2x
= 2(24)
= 48
So, the son is 24 and the father is 48. 
10 years ago, son was 14 and father was 38, if added, this adds up to 52, so we know our calculations are correct.
