1. **State the problem:** 17 more than a number is 43. Find the number. 2. **Choose the correct equation:** The problem translates to the equation $$17 + n = 43$$ where $n$ is the unknown number. 3. **Solve the equation:** $$17 + n = 43$$ Subtract 17 from both sides to isolate $n$: $$\cancel{17} + n - \cancel{17} = 43 - 17$$ This simplifies to: $$n = 26$$ 4. **Interpretation:** The number is 26. **Final answer:** $n = 26$
