Question

solve for u.
9u = 3u + 54

Explanation:

Step1: Subtract \(3u\) from both sides

To isolate the variable \(u\), we first subtract \(3u\) from both sides of the equation \(9u = 3u + 54\). This gives us \(9u - 3u = 3u + 54 - 3u\). Simplifying both sides, we have \(6u = 54\).

Step2: Divide both sides by 6

Next, we divide both sides of the equation \(6u = 54\) by 6 to solve for \(u\). So, \(\frac{6u}{6}=\frac{54}{6}\), which simplifies to \(u = 9\).

Answer:

\(u = 9\)
