Answer 2

To solve the equation 1/3(3x - 6) - 2/7(7x - 21) = 9/(-fraction), you'll want to first simplify the equation and then solve for x.

Let's simplify the equation step by step:

1. Distribute the fractions on the left side: (1/3) * (3x - 6) - (2/7) * (7x - 21) = 9/(-fraction)

   Simplify within the parentheses:

   (x - 2) - (2x - 6) = 9/(-fraction)

2. Continue to simplify the equation:

   Now, distribute the negative sign on the right side:

   x - 2 - 2x + 6 = 9/(-fraction)

3. Combine like terms:

   (x - 2x) + (-2 + 6) = 9/(-fraction)

   -x + 4 = 9/(-fraction)

4. Multiply both sides by (-fraction) to isolate the variable:

   -x * (-fraction) + 4 * (-fraction) = 9

   This changes the sign of the equation:

   x * fraction - 4 * fraction = 9

5. Now, you can add 4 * fraction to both sides:

   x * fraction = 9 + 4 * fraction

6. Finally, divide both sides by the fraction to solve for x:

   x = (9 + 4 * fraction) / fraction

Please note that if you provide the specific value of the fraction in the equation, we can calculate the exact value of x. If you meant to provide a specific fraction, please specify its value, and I can help you further.
