1. **State the problem:** Simplify the expression $7z + 9 + 2z + 2$.
2. **Combine like terms:** Group the terms with $z$ and the constant terms separately.
$$7z + 2z + 9 + 2$$
3. **Add the coefficients of $z$:**
$$7z + 2z = (7 + 2)z = 9z$$
4. **Add the constant terms:**
$$9 + 2 = 11$$
5. **Write the simplified expression:**
$$9z + 11$$
**Final answer:** $9z + 11$
