You can put this solution on YOUR website! Julius is 96 years old.
He is twice as old sean was, when julius was as old as sean.
How old is sean now?
:
let s = Sean's present age
let d = (96-s), the difference in their ages
2(s - d) = 96
simplify, divide by 2
s - d = 48
replace d with (96-s)
s-(96-s) = 48
s - 96 + s = 48
2s = 48 + 96
2s = 144
s = 144/2
s = 72 yrs is Sean's age
