Question 1134183
Ben is 30 years old and Daniel is 2 years old.
How many years will it take until Ben is only 3 times as old as Daniel?
:
let y = no. of years for this to be true
30 + y = 3(2+y)
30 + y = 6 + 3y
30 - 6 = 3y - y
24 = 2y
y = 24/2
y = 12 years, Ben will be 3 times Daniel
:
:
Check their ages in 12 years
30 + 12 = 3(2+12)
42 = 3(14)
