2 Nolan Ryan Cards = 6 Will Clark Cards + 3 Jose Canseco Cards (Equation 1)
9 Jose Canseco cards = 12 Will Clark Cards + 2 Nolan Ryan Cards (Equation 2
Substitute the value of Nolan Ryan Cards from equation 1 into equation 2.
9 Jose Canseco cards = 12 Will Clark Cards+6 Will Clark Cards + 3 Jose Canseco
Cards
6 Jose Canseco cards = 18 Will Clark Cards
So 1 Jose Canseco card = 3 Will Clark Cards
Using that information back in equation 1
