Question

solve for u. 2(u + 2) = 18 u =

Explanation:

Step1: Divide both sides by 2

To isolate the term with \( u \), we divide both sides of the equation \( 2(u + 2)=18 \) by 2.
\[
\frac{2(u + 2)}{2}=\frac{18}{2}
\]
Simplifying both sides, we get \( u + 2 = 9 \).

Step2: Subtract 2 from both sides

To solve for \( u \), we subtract 2 from both sides of the equation \( u + 2 = 9 \).
\[
u+2 - 2=9 - 2
\]
Simplifying both sides, we find that \( u = 7 \).

Answer:

\( 7 \)
