Answer 2

Ответ:

Пошаговое объяснение:

-2a+11b-(4+3b-9a)-6a-8b+6=-2a+11b-4-3b+9a-6a-8b+6=(-2a+9a-6a)+(11b-3b-8b)+(6-4)=a+2

Answer 3

Let's simplify the expression step by step:

1. Start by simplifying the terms inside the parentheses:

   -(2a - 11b) - (4 + 3(b - 3a)) - 2(3a + 4b - 3)

   = -(2a - 11b) - (4 + 3b - 9a) - (6a + 8b - 6)

2. Distribute the negative sign to the terms inside the first set of parentheses:

   = -2a + 11b - (4 + 3b - 9a) - (6a + 8b - 6)

3. Now, distribute the negative sign to the second set of parentheses:

   = -2a + 11b - 4 - 3b + 9a - (6a + 8b - 6)

4. Continue simplifying by combining like terms:

   = (-2a + 9a) + (11b - 3b) - 4 + 6 - 8b + 6

5. Combine like terms in each pair of parentheses:

   = 7a + 8b - 4 + 6 - 8b + 6

6. Combine like terms in the remaining expression:

   = 7a + 0 - 4 + 6

7. Simplify further:

   = 7a - 4 + 6

8. Finally, combine the constants:

   = 7a + 2

So, -(2a - 11b) - (4 + 3(b - 3a)) - 2(3a + 4b - 3) simplifies to 7a + 2.
