Question: User: $-3y=0$
1. **State the problem:** Solve the equation $$-3y=0$$ for the variable $y$.
2. **Formula and rules:** To solve for $y$, we need to isolate $y$ on one side of the equation. Since $y$ is multiplied by $-3$, we will divide both sides of the equation by $-3$.
3. **Intermediate work:**
$$-3y=0$$
Divide both sides by $-3$:
$$\frac{-3y}{\cancel{-3}}=\frac{0}{\cancel{-3}}$$
4. **Simplify:**
$$y=0$$
5. **Explanation:** Dividing both sides by $-3$ cancels the coefficient of $y$, leaving $y$ alone. Since $0$ divided by any nonzero number is $0$, the solution is $y=0$.
**Final answer:**
$$y=0$$
