1. **State the problem:** Solve the inequality $$-22 \leq x + 8$$ for $x$. 2. **Isolate $x$:** To solve for $x$, subtract 8 from both sides of the inequality. 3. **Apply subtraction:** $$-22 - 8 \leq x + 8 - 8$$ 4. **Simplify both sides:** $$-30 \leq x$$ 5. **Rewrite the inequality:** This means $$x \geq -30$$. **Answer:** The number that belongs in the green box is **-30**. This means $x$ is greater than or equal to $-30$.
