Rachel and Sharon are splitting up their Pokemon cards. Rachel has 4 fewer than 3 times as many as Sharon. Together they have 100 cards. Which equation could be used to solve for how many cards Sharon had originally? Let n = number of cards that Sharon had.

• n + (3n - 4) = 100

• n - (3n - 4) = 100

• n + (4 - 3n) = 100

• 4 - 3n = 100
