Please Help,

How do i work this out ?

Uncle Scrooge has asked for a strange bequest in his will. Huey is to receive 3 times as much as Duey, while Louie is to receive twice as much as Duey MINUS 1 Dollar. If the total amount to be divided between them if 107 Million Dollars, calculate how much each has to inherit.

Please reply ASAP.

Thanks
