In 16 years, Ben will be 3 times as old as he is right now.
Let Ben's age right now be b.
We have, in 16 years, Ben's age will be 3 times what his age is now:
b + 16 = 3b
Subtract b from each side:
2b = 16
Divide each side by 2
b = 8
Check our work:
16 years from now, Ben's age is 8 + 16 = 24
And, 8 x 3 = 24
