Use the information to write an equation with variables on both sides. Let x represent Kim's age. Bob is 4 years older than twice Kim's age. Paul is 1 year younger than 3 times Kim's age. Bob and Paul are the same age. Which equation can be used to determine Kim's age, x, from the information about Bob and Paul? 4x + 2 = 3x + 1 4x + 2 = 3x + (–1) 2x + 4 = 3x + 1 2x + 4 = 3x + (–1)
