Question 388994
Jeff is Three times as old as his son. In nine years, Jeff will be twice as old as his son.   How old is each now?

Let son's age = x
Jeff age = 3x
..
after 9 years
son = x+9 years
Jeff = 3x+9 years
..
3x+9=2(x+9)
..
3x+9 = 2x+18
-2x
3x-2x+9 = 18
x+9=18
-9
x=18-9
x=9... Son's age
Jeff's age = 3x = 27 years
