Seth has one less than twice the number of compact discs (CDs) thatJason has. Raoul has 53 more CDs than Jason has. If Seth gives Jason25 CDs, Seth and Jason will have the same number of CDs. How many CDs did each of the three boys have to begin with?

My work:

Seth = (2x-1) - 25

Jason = x + 25

Raoul = x + 53

I got stuck there.
