[quote=Anonymous]When students are not undestanding, I try to break the process into smaller steps in translating: "seven more slices of pepperoni pizza than cheese pizza" So the number of cheese slices + 7 is the number of pepperoni slices C + 7 = P The total number of slices is 15 The number of cheese slices and pepperoni slices = total number of slices C + P = 15 So combining those two equations above C + P = 15 C + (C + 7) = 15 since + and - are all equal priority (C + C) + 7 = 15 (C + C) + 7 - 7 = 15 - 7 (C + C) = 8 2C = 8 C = 4 So Cheese slices is 4 and Pepperoni slices = (C + 7) or 11 [/quote]
