Answer 2

Let's simplify the given expression step-by-step:

1. Combine like terms for the variables 'x': 6x - 8x - x = (6 - 8 - 1)x = -3x

2. Combine like terms for the variables 'a': -a - 5a + 7a = (-1 - 5 + 7)a = (1)a = a

3. Combine like terms for the constant terms (numbers without variables): 3 + 3 = 6

4. Combine like terms for the variables 'b': 5b - (4 - b) = 5b - 4 + b = 6b - 4

Now, putting it all together, the simplified expression is: -3x + a + 6 + 6b - 4

Please note that if the expression was intended to include the variables 'a' and 'b' as coefficients of constants (e.g., "a" multiplied by "-a" or "5b" multiplied by "(4-b)"), the simplification would be different. However, from the given expression, it appears that we are simplifying only the expression without performing any multiplication between variables and constants.
