1. **State the problem:** Solve for $s$ in the equation $$5s + 2s + 4s - 5s = 6$$. 2. **Combine like terms:** Add and subtract the coefficients of $s$ on the left side. $$5s + 2s + 4s - 5s = (5 + 2 + 4 - 5)s = 6s$$ 3. **Rewrite the equation:** $$6s = 6$$ 4. **Solve for $s$ by dividing both sides by 6:** $$s = \frac{6}{6}$$ 5. **Simplify the fraction:** $$s = \cancel{\frac{6}{6}} = 1$$ **Final answer:** $$s = 1$$
