### Simplifying Algebraic Expressions

**Problem Statement:**

How many twenty-dollar bills would have a value of \$(60x - 40)?  (Simplify your answer completely.)

**Explanation:**

To solve this problem, you need to determine the total value expressed by the algebraic expression \(60x - 40\) dollars and then find how many twenty-dollar bills are equivalent to this amount. Here are the steps you can follow:

1. **Simplify the Expression**:
   - Combine like terms in the expression \(60x - 40\).

2. **Value in Terms of Twenty-Dollar Bills**:
   - Divide the simplified expression by 20 (since each twenty-dollar bill is worth $20).
   - This division will give you the number of twenty-dollar bills that make up the given amount.

**Solution**:

1. Given expression: \(60x - 40\) dollars
2. To find how many twenty-dollar bills make up this value, divide this by 20:

   \[
   \frac{60x - 40}{20}
   \]

3. Simplify the fraction:

   \[
   \frac{60x}{20} - \frac{40}{20}
   \]

4. Perform the division:

   \[
   3x - 2
   \]

   So, \(3x - 2\) twenty-dollar bills are equivalent to the given expression \((60x - 40)\) dollars.

**Conclusion**:

The number of twenty-dollar bills that would have the value of \((60x - 40)\) dollars is \((3x - 2)\).
