Step-by-step explanation:

40 + 6x =  - 7(4x + 4) \\ 40 + 6x =  - 28x - 28 \\ 6x + 28x =  - 28 - 40 \\ 34x =    - 68 \\  \\ x =  -  \frac{68}{34}  \\  \\ x =  - 2

Answer:

x = -2

Step-by-step explanation:

40+6X = -7(4x+4)

Distribute

40 +6x = -28x -28

Add 28x to each side

40 + 6x +28x = -28x-28 +28x

40 + 34x = 28

Subtract 40 from each side

40 + 34x -40 = -28-40

34x = -68

Divide each side by 34

34x/34 = -68/34

x = -2
