Question: User: $-9p-10=-64$
1. **State the problem:** Solve the equation $-9p - 10 = -64$ for $p$.
2. **Add 10 to both sides:**
$$-9p - 10 + 10 = -64 + 10$$
$$-9p = -54$$
3. **Divide both sides by $-9$ to isolate $p$:**
$$p = \frac{-54}{-9}$$
4. **Simplify the fraction:**
$$p = \frac{\cancel{-54}}{\cancel{-9}} = 6$$
5. **Final answer:**
$$p = 6$$
This means the value of $p$ that satisfies the equation is $6$.
