Answer:
PETER 18
POL 21
MARY 26
Step-by-step explanation:
I dont know if I did in the right way...
1st: Take any number for peter's or pol's age
I took 18 for peter, RANDOMLY
2nd: Subtract the age from the total to get pol's age
39-18=21 Hence, pols age is 21
3rd: Subtract peter's age from the total to get marys age
47-18=26 Hence, Marys age is 26
4th: Add the age of pol and mary
aaand, you get 47
Done!
