To find the solution to the inequality $-5 \leq \frac{x + 6}{12} \leq 5$, we first solve for $x$ in the inequality. Multiplying all parts by 12 gives $-60 \leq x + 6 \leq 60$. Subtracting 6 from all parts gives $-66 \leq x \leq 54$. Thus, any $x$ outside the range $[-66, 54]$ is not a solution. $x = -68$ is outside this range, making it the correct answer.
