1. **State the problem:** Solve for $W$ in the equation $$7 = L W$$. 2. **Formula and rules:** To isolate $W$, divide both sides of the equation by $L$, assuming $L \neq 0$. 3. **Intermediate work:** $$7 = L W$$ Divide both sides by $L$: $$\frac{7}{\cancel{L}} = \frac{L W}{\cancel{L}}$$ 4. **Simplify:** $$W = \frac{7}{L}$$ 5. **Explanation:** We divided both sides by $L$ to isolate $W$. This works because dividing by the same nonzero number on both sides keeps the equation balanced. **Final answer:** $$W = \frac{7}{L}$$
