1. **State the problem:** Solve the equation $-15 = 5 - 8 - 4h$ for $h$. 2. **Simplify the right side:** $$5 - 8 - 4h = (5 - 8) - 4h = -3 - 4h$$ 3. **Rewrite the equation:** $$-15 = -3 - 4h$$ 4. **Isolate the term with $h$ by adding 3 to both sides:** $$-15 + 3 = -3 - 4h + 3$$ $$-12 = -4h$$ 5. **Divide both sides by $-4$ to solve for $h$:** $$h = \frac{-12}{-4}$$ 6. **Simplify the fraction by canceling common factors:** $$h = \frac{\cancel{-12}}{\cancel{-4}} = 3$$ **Final answer:** $$h = 3$$
