Ответ:

Пошаговое объяснение:

3) 7 + 4 x - 11 - 9 x - 11 - 8 = -5х -23

4) 5x + 4 - 6 - 3x + 4 + 8 =  2х + 10

Answer 2

Let's simplify each expression step by step:

3. 7 + 4x - 11 - 9x - 11 - 8

Combine like terms:

(4x - 9x) = -5x (7 - 11 - 11 - 8) = -23

So, the simplified expression is:

-5x - 23

4. 5x + 4 - 6 - 3x + 4 + 8

Combine like terms:

(5x - 3x) = 2x (4 - 6 + 4 + 8) = 10

So, the simplified expression is:

2x + 10
