For this case we have the following equation:
![2 (x + 2) = x-4](https://tex.z-dn.net/?f=2%20%28x%20%2B%202%29%20%3D%20x-4)
Applying distributive property to the terms within the parentheses on the left side of the equation we have:
![2x + 4 = x-4](https://tex.z-dn.net/?f=2x%20%2B%204%20%3D%20x-4)
Subtracting "x" on both sides of the equation we have:
![2x-x + 4 = -4\\x + 4 = -4](https://tex.z-dn.net/?f=2x-x%20%2B%204%20%3D%20-4%5C%5Cx%20%2B%204%20%3D%20-4)
Subtracting 4 on both sides of the equation we have:
![x = -4-4\\x = -8](https://tex.z-dn.net/?f=x%20%3D%20-4-4%5C%5Cx%20%3D%20-8)
Answer:
![x = -8](https://tex.z-dn.net/?f=x%20%3D%20-8)
