To solve this inequality, we can proceed as follows:
1. Apply the distributive property at the left side of the inequality:

2. We can add 8x to both sides of the inequality:

And we obtain that 8 > 6. This is always true. Therefore, we can say that all the real numbers satisfy the inequality, and we can select All Real Numbers.
In summary, all real numbers satisfy the inequality. Then the answer is All Real Numbers.
