3.) -25 - 19x

4.) 27x - 4

Step-by-step explanation:

1. 8 - 6x + 2y - 10 + 10x

-2 - 6x + 2y + 10x

4x - 2 + 2y

2. 9 (5 - 2y)

45 - 18y

3. 7 + 5x - 8 ( 3x + 4 )

7 + 5x -24x - 32

-25 + 5x - 24x

-25 - 19x

4. 12 + 10x + 2 ( 6x - 8) + 5x

12 + 10x + 12x - 16 + 5x

15x + 12x + 12 - 16

27x + 12 - 16
