Question: User: $-72=18v$
1. **State the problem:** Solve the equation $$-72 = 18v$$ for the variable $$v$$.
2. **Formula and rules:** To isolate $$v$$, divide both sides of the equation by the coefficient of $$v$$, which is $$18$$.
3. **Intermediate work:**
$$\frac{-72}{18} = \frac{18v}{18}$$
$$\frac{\cancel{-72}}{\cancel{18}} = v$$
4. **Simplify the fraction:**
$$-4 = v$$
5. **Final answer:**
$$v = -4$$
This means that when $$v$$ is $$-4$$, the equation $$-72 = 18v$$ holds true.
