Answer:
Step-by-step explanation:
Let c represent Chanda's age now. In six years, the Sokhem's age will be 2c. At that time, the sum of their ages is ...
(c+6) +2c = 60
3c = 54 . . . . . . . . subtract 6, collect terms
c = 18 . . . . . . . . . . divide by 3
Chanda is 18, Sokhem is 30.

<em>Check</em>
In 6 years Chanda will be 24, Sokhem will be 36. The sum of their ages then will be 24+36 = 60. Since Chanda is 18 now, Sokhem's age then will be 2 times Chanda's age now.
