.Kim is x years old. Jordan is 7 years older than Kim. Four times Jordan’s age is equal to 200. (a)Write an equation that could be used to solve for Kim’s age, x. (b)How old is Kim? (c)How old is Jordan? Answer:
Kim = x Jordan = x + 7
4(x+7) = 200 4x + 28 = 200 4x = 200 - 28 4x = 172 x = 172/4 x = 43. Kim's age
