Dylan's age =
p years
Peter's age = 6
p years
Neave's age = (6
p - 9) years
(b)
p = 5
Difference in age remains unchanged.
Difference in age between Neave and Dylan

p - 9) -
p = 6
p -
p - 9
= 5
p - 9
= 5 x 5 - 9
= 16 years
Difference in the age when Neave will be 3 times as old as Dylan
= 3 u - 1 u
= 2 u
2 u = 16
1 u = 16 ÷ 2 = 8
Number of years' time so Neave will be 3 times as old as Dylan
