I want to know if my set up is correct.\n\n1. In 20 years, Kayleen will be four times older than she is today. What is her current age?\n\nLet x = Kayleen's current age.\nLet x + 20 = Kayleen's age in 20 years.\n\nx + 20 = 4x\n\nYou say? \n\n2. 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?\n\nJohn's age now = 2(x + 5)\n\nPeter's age now = x + 5\n\nAlice's age now = x\n\n2(x + 5) = 3x\n\nLet me try this one.\n\n2x + 10 = 3x\n\n10 = 3x - 2x\n\n10 = x\n\nPeter = x + 5 or 10 + 5 = 15 years old. \n\nYes?
