Question

solve for z.
2(5 + z) = 16
z = ?

Explanation:

Step1: Divide both sides by 2

To isolate the term with \( z \), we divide both sides of the equation \( 2(5 + z)=16 \) by 2.
\( \frac{2(5 + z)}{2}=\frac{16}{2} \)
Simplifying both sides, we get \( 5 + z = 8 \).

Step2: Subtract 5 from both sides

To solve for \( z \), we subtract 5 from both sides of the equation \( 5 + z = 8 \).
\( 5 + z-5 = 8 - 5 \)
Simplifying both sides, we get \( z = 3 \).

Answer:

\( z = 3 \)
