Armand is playing a guessing game with his dad where he has to guess a number his dad is thinking of. His dad tells him that the number, when multiplied by 3, is three less than twice 51. What is the number? Let's answer step by step:
102 is twice 51 because 2 x 51 = 102. Three less than 102 is 99 because 102 - 3 = 99. The number is 33 because 99 / 3 = 33. The answer: 33.
