Eve and Julian are making their own pizzas. Eve's crust weighs 18 ounces, and Julian's crust weighs 12 ounces. After Eve adds 4 spoonfuls of tomato sauce to her pizza and Julian adds 8 spoonfuls to his, the two pizzas weigh the same. Which equation can you use to find \( w \), the weight of a spoonful of tomato sauce in ounces? \[ 18+4 w=12 w+8 \] How much does a spoonful of tomato sauce weigh? Simplify any fractions. ounces
