Let h=Harold, j=jack, and d=dan. If Harold is twice as old as jack then you could write this relationship as
For instance if jack is 10, then harold is 20
And if jack is 3 years older than dan then it can be written as

And if harold's age is 5 times dan's age then

First set the 2 h equations equal to each other
Solve for d

Then plug this equation of d into d of the equation d+3=j

Plug in
Subtract (2/5)j from both sides
subtract fractions
solve for j

So jack is 5 years old, harold is 10, and dan is 2
