To solve the compound inequality $-31 \leq -5z - 1 \leq -11$, first add 1 to all parts: $-30 \leq -5z \leq -10$. Then divide by -5 and reverse the inequality signs: $6 \geq z \geq 2$, which is equivalent to $2 \leq z \leq 6$. This corresponds to the interval $[2, 6]$.

Solve - −31≤−5z−1≤−11- 31 \leq - 5 z - 1 \leq - 11−31≤−5z−1≤−11

Solve
- $- 31 \leq - 5 z - 1 \leq - 11$
