Problem
The weight of of a large pizza together with cups of orange slices is the same as the weight of of a large pizza together with cup of orange slices. A cup of orange slices weighs of a pound. What is the weight, in pounds, of a large pizza?
Solution 1 (Substitution)
Use a system of equations. Let be the weight of a pizza and be the weight of a cup of orange slices. We have Rearranging, we get Plugging in pounds for by the given gives

Solution 2
Let: be the weight of a pizza. be the weight of a cup of orange.
From the problem, we know that .
Write the equation below:
Solving for :
~d_code
Solution 3
where is the pizza weight and is the weight of cup of oranges Since oranges weigh pound per cup, the oranges on the LHS weigh cups x pounds/cup = pound, and those on the RHS weigh cup x pounds/cup = pound.
So + pound = + pound; + pound = .
Multiplying both sides by , we have ; ; = weight of a large pizza = pounds = pounds.
