Explanation:

Step1: Divide both sides by 3

To isolate the term with \( z \), we divide both sides of the equation \( 3(z + 2)=9 \) by 3. This gives us \( \frac{3(z + 2)}{3}=\frac{9}{3} \), which simplifies to \( z + 2 = 3 \).

Step2: Subtract 2 from both sides

To solve for \( z \), we subtract 2 from both sides of the equation \( z + 2 = 3 \). So, \( z + 2 - 2 = 3 - 2 \), which simplifies to \( z = 1 \).

Answer:

\( z = 1 \)
