Answer 2

To simplify the expression -7(4 - a) + 4(-3a - 3) - 6(-8 + a), you can use the distributive property to expand each term and then combine like terms. Here's the step-by-step simplification:

1. Start with the expression: -7(4 - a) + 4(-3a - 3) - 6(-8 + a).

2. Use the distributive property for each term: -7 * 4 + 7 * a + 4 * -3a - 4 * (-3) - 6 * -8 + 6 * a.

3. Multiply the numbers: -28 + 7a - 12a + 12 + 48 + 6a.

4. Combine like terms: (7a - 12a + 6a) + (-28 + 12 + 48).

5. Further simplify: a - 28 + 12 + 48.

6. Combine constants: a - 28 + 60.

7. Finally, simplify the constants: a + 32.

So, the simplified expression is a + 32.
