Answer 3

Everything you need is already given. Assuming that both Jack and Tom are still alive, we know that since last year Jack is 15 years older than Tom, this year he is still 15 years older. In order for Jack to ever be twice as old as Tom, Jack must be 30 years old and Tom 15 years old.

Answer 4

oh i see

Answer 5

A set of equations might look like this:

x = Jack's Age
y = Tom's Age

1. x - y = 15
2. x = 2y

Solving for x and y give you 30 and 15
