Question

solve for u.
6(u + 3) = 72
simplify your answer as much as possible.
u =

Explanation:

Step1: Divide both sides by 6

To isolate the term with \( u \), we divide both sides of the equation \( 6(u + 3)=72 \) by 6.
\[
\frac{6(u + 3)}{6}=\frac{72}{6}
\]
Simplifying both sides, we get \( u + 3 = 12 \).

Step2: Subtract 3 from both sides

To solve for \( u \), we subtract 3 from both sides of the equation \( u + 3 = 12 \).
\[
u+3 - 3=12 - 3
\]
Simplifying both sides, we find that \( u = 9 \).

Answer:

\( u = 9 \)
