1. **State the problem:** Solve the inequality $d > 6$. 2. **Formula and rules:** For inequalities, if you add or subtract the same number on both sides, the inequality remains the same. If you multiply or divide by a positive number, the inequality direction remains the same. 3. **Solve the inequality:** The inequality is already solved for $d$: $$d > 6$$ 4. **Interpretation:** This means $d$ can be any number greater than 6. 5. **Final answer:** $$d > 6$$ This is the solution set for the first inequality.
