Jorge (J), Marcus (M) and Ren (R) want to pool their Pokemon cards together. Jorge has two times the amount of cards that Marcus has. Ren has 24 more cards than Marcus. Together their cards add up to 2000. Write an equation to represent this situation and use it to solve for how many cards each person contributes to the pool. (Hint: Write equations for Jorge and Ren with Marcus as the variable)
