First, let's ignore the answer choices and solve for a value of x ourselves.
2(8 - x) < 4
Distributive property.
16 - 2x < 4
Subtract 16 from both sides.
-2x < -12
Divide both sides by -2 (and flip the inequality sign)
x > 6
The value of x is going to be greater than 6, and so, we can observe the answer choices, and whichever value is greater than 6, is the correct answer.
In this case, there is only one answer, and that is D, x = 10.
