Answer 2

Task Formulation

To create a problem that can be solved using the equation 2(????+3)−????=15, we can frame it as a real-world scenario. Let's consider the following situation:

Scenario: A store sells two types of items. The first type costs $3 more than the second type. If a customer buys two of the first type and one of the second type, the total cost is $15. We can then ask the question: What is the cost of each type of item?

Solution Approach

To solve this problem, we can use the given equation 2(????+3)−????=15, where ???? represents the cost of the second type of item. By solving for ????, we can determine the cost of each type of item.

Solution Steps

1. Define Variables: Let's define ???? as the cost of the second type of item. 2. Formulate Equation: Using the given information, we can set up the equation 2(????+3)−????=15. 3. Solve for ????: We'll solve the equation to find the value of ????, which represents the cost of the second type of item. 4. Calculate Total Costs: With the value of ????, we can calculate the cost of each type of item.

Solution

The problem can be solved using the equation 2(????+3)−????=15, where ???? represents the cost of the second type of item. By solving for ????, we can determine the cost of each type of item in the given scenario.
