Final answer:
The solution to the equation -8 = x + 4 is x = -12 after subtracting 4 from both sides, which is not listed in the options provided. Thus, the correct answer is D. None of the above.
Step-by-step explanation:
The solution to the equation -8 = x + 4 is found by isolating the variable x on one side of the equation. To find the value of x, you subtract 4 from both sides of the equation as follows:
-8 = x + 4
-8 - 4 = x + 4 - 4
-12 = x
Therefore, the correct answer is x = -12, which is not among the options A, B, or C. Hence, the correct choice is D. None of the above.
