Asked by Kelvin

Coach Johnson is 10 years older than Tim. When Tim started football 3 years ago, Coach Johnson was twice his age. How old is Tim now?
Answered by Reiny
Tim's current age -- x
coach's current age -- x+10

3 yrs ago, Tim was x-3
3 yrs ago, coach was x+7

(x+7) = 2(x-3)
x+7 = 2x - 6
13 = x

Tim is now 13


check: if Tim is 13, then coach is 23
3 years ago, Tim was 10 , coach was 20
Yes, he was twice as old then!
