I want to know if my set up is correct. 1. In 20 years, Kayleen will be four times older than she is today. What is her current age? Let x = Kayleen's current age. Let x + 20 = Kayleen's age in 20 years. x + 20 = 4x You say? 2. John is twice as old as his friend Peter. Peter is 5 years older than Alice. In 5 years, John will be three times as old as Alice. How old is Peter now? John's age now = 2(x + 5) Peter's age now = x + 5 Alice's age now = x 2(x + 5) = 3x Let me try this one. 2x + 10 = 3x 10 = 3x - 2x 10 = x Peter = x + 5 or 10 + 5 = 15 years old. Yes?
