You can put this solution on YOUR website!
let Ashly’s age be x and his Jerar’s age y
if Ashly is twice as old as Jerar:
x=2y....eq.1
In three years, the sum of their ages will be 54, then
%28x%2B3%29%2B%28y%2B3%29+=54........substitute x
2y%2By=54-6
3y=48
y=16
go to
x=2y....eq.1,....substitute y
x=2%2A16
x=32
so, Ashly is 32 and Jerar is 16 years old
