In 2004 Jeremiah is five times the age of his cousin Karen. In 2009 he is three times her age. How old was Jeremiah in 2004?
**
In2004
let x=Karen's age
5x=Jeremiah's age
..
In2009 (5 yrs hence)
x+5=Karen's age
5x+5=Jeremiah's age
Jeremiah is 3 times the age of Karen
5x+5=3(x+5)
5x+5=3x+15
2x=10
x=5
5x=25
Jeremiah's age in 2004=25
