1. **State the problem:** Solve for the variable $s$ in the equation $8 + s = 14$. 2. **Formula and rules:** To isolate $s$, subtract 8 from both sides of the equation. This uses the property of equality: if you do the same operation on both sides, the equality holds. 3. **Intermediate work:** $$8 + s = 14$$ Subtract 8 from both sides: $$\cancel{8} + s - \cancel{8} = 14 - 8$$ 4. **Simplify:** $$s = 6$$ 5. **Explanation:** We removed 8 from the left side to leave $s$ alone, and did the same on the right side to keep the equation balanced. The value of $s$ is 6.
