1. **State the problem:** Solve for $h$ in the equation $$-2.3 = \frac{h + 4.3}{-1}$$. 2. **Understand the equation:** The right side is a fraction with denominator $-1$. Dividing by $-1$ changes the sign of the numerator. 3. **Multiply both sides by $-1$ to eliminate the denominator:** $$-2.3 \times \cancel{-1} = (h + 4.3) \div \cancel{-1}$$ which simplifies to $$2.3 = h + 4.3$$ 4. **Isolate $h$ by subtracting $4.3$ from both sides:** $$2.3 - \cancel{4.3} - 4.3 = h + \cancel{4.3} - 4.3$$ which simplifies to $$h = 2.3 - 4.3$$ 5. **Calculate the right side:** $$h = -2.0$$ **Final answer:** $$h = -2.0$$
