Answer:
Thomas age will be 27 yrs old.
Step-by-step explanation:
Let the Thomas age be x
- Huilan is 12 yrs older than Thomas = x + 12
- The sum of their ages = 66
➛ x + 12 + x = 66
➛ 2x + 12 = 66
subtract 12 from 66
➛2x = 66 - 12
➛2x = 54
divide 2 from each side
➛ x = 54 / 2
➛ x = 27
- Huilan age = 27 + 12 = 39 yrs old
- Thomas age = 27 yrs old
