question
solve.
5(z + 2) = 15
answer attempt 1 out of x

Explanation:

Step1: Divide both sides by 5

To isolate the term with \( z \), we divide both sides of the equation \( 5(z + 2)=15 \) by 5.
\[
\frac{5(z + 2)}{5}=\frac{15}{5}
\]
Simplifying both sides, we get \( z + 2 = 3 \).

Step2: Subtract 2 from both sides

To solve for \( z \), we subtract 2 from both sides of the equation \( z + 2 = 3 \).
\[
z + 2 - 2 = 3 - 2
\]
Simplifying both sides, we find that \( z = 1 \).

Answer:

\( z = 1 \)
