Answer 3

To solve the equation, let's break it down step by step:

1. Start with the equation: 3 × (2 3/5 - x) = 3 1/5 = 4 1/3.

2. Convert the mixed numbers to improper fractions:

   • 2 3/5 = (2 × 5 + 3) / 5 = 13/5.
   • 3 1/5 = (3 × 5 + 1) / 5 = 16/5.
   • 4 1/3 = (4 × 3 + 1) / 3 = 13/3.

3. Substitute the fractions back into the equation: 3 × (13/5 - x) = 16/5 = 13/3.

4. Simplify the equation: Multiply both sides of the equation by 5 to eliminate the denominators: 3 × (13/5 - x) × 5 = 16/5 × 5 = 13/3 × 5.

   Simplify: 3 × 13 - 15x = 52/3.

   Multiply: 39 - 15x = 52/3.

5. Convert the fraction to a mixed number: 52/3 = 17 1/3.

   Rewrite the equation: 39 - 15x = 17 1/3.

6. Convert the mixed number to an improper fraction: 17 1/3 = (17 × 3 + 1) / 3 = 52/3.

   Rewrite the equation: 39 - 15x = 52/3.

7. To eliminate the fraction, multiply both sides of the equation by 3: 3 × (39 - 15x) = 3 × (52/3).

   Simplify: 117 - 45x = 52.

8. Move the constant term to the other side of the equation: 117 - 52 = 45x.

   Simplify: 65 = 45x.

9. Divide both sides of the equation by 45 to solve for x: x = 65/45.

10. Simplify the fraction if possible: x = 13/9.

Therefore, the solution to the equation 3 × (2 3/5 - x) = 3 1/5 = 4 1/3 is x = 13/9.
