Question

solve for u.
9 = 5u + 27 + 4u
simplify your answer as much as possible.
u =

Explanation:

Step1: Combine like terms

Combine the \( u \)-terms on the right side: \( 5u + 4u = 9u \), so the equation becomes \( 9 = 9u + 27 \).

Step2: Subtract 27 from both sides

Subtract 27 from each side: \( 9 - 27 = 9u + 27 - 27 \), which simplifies to \( -18 = 9u \).

Step3: Divide by 9

Divide both sides by 9: \( \frac{-18}{9} = \frac{9u}{9} \), so \( u = -2 \).

Answer:

\( u = -2 \)
