Caden's age =
v years
Elijah's age = 5
v years
Vaidev's age = (5
v - 8) years
(b)
v = 9
Difference in age remains unchanged.
Difference in age between Vaidev and Caden

v - 8) -
v = 5
v -
v - 8
= 4
v - 8
= 4 x 9 - 8

Difference in the age when Vaidev will be 3 times as old as Caden
= 3 u - 1 u
= 2 u
2 u = 28
1 u = 28 ÷ 2 = 14
