Example The weight of Keiko's kitten is the weight of her puppy. If each animal gains 3 pounds, the kitten will weigh as much as the puppy. The equation w + 3 = (w + 3) describes this situation, where w is the weight of the puppy now. How much does the puppy weigh now? 6w+ 3) = 6. + 3 = 2(w + 3) w + 18 = 2w + 6 w - w + 18 = 2w – w + 6 18 = w + 6 12 = w The puppy weighs 12 pounds now. 1 In the Example, how much will the kitten weigh if it gains 3 pounds? Show your work. SOLUTION
