You can put this solution on YOUR website! :
"When Juan was 12 his father was three times his age.
j = 12, f=36
" Now his father is only twice Juan's age."
let y = the no. of years for this to be true
y + 36 = 2(y + 12)
Y + 36 = 2Y + 24
36 - 24 = 2Y - Y
12 = Years for the f to be twice as old as j
:
How old are they now?
36 + 12 = 48 yrs is f's age now
12 + 12 = 24 yrs is j's age
