Question 271142
In 2000, my husband John was eleven times as old as my son William. In 2012, he will be three times as old as my son. How old was my son of 2000?


let william's age be x in year 2000

in year 2000 John's age was 11x

After 12 years 11x+12 = 3(x+12)

11x+12 = 3x +36

11x-3x=36-12
8x=24

x=3

The son was 3 years old in year 2000.
