Jamie and Cynthis sold a total of 84 raffle tickets. Jamie sold 3 fewer than twice the number Cynthis sold. Which system of equations could be used to determine the number of raffle tickets sold by Jamie, j, and Cynthia, c?

• j + c = 84

  j = 3 - 2c

• j + c = 84

  c = 2j +3

• j + c = 84

  j = 3c + 2

• j + c = 84

  j = 2c -3
