5(z + 2) = 15

answer attempt 1 out of 2
z =
submit answer

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:

\( z = 1 \)
