Question

solve for u. 9u = 12 + 5u simplify your answer as much as possible. u =

Explanation:

Step1: Subtract 5u from both sides

To isolate the variable terms on one side, we subtract \(5u\) from both sides of the equation \(9u = 12 + 5u\). This gives us \(9u - 5u = 12 + 5u - 5u\). Simplifying both sides, we have \(4u = 12\).

Step2: Divide both sides by 4

To solve for \(u\), we divide both sides of the equation \(4u = 12\) by 4. So, \(\frac{4u}{4}=\frac{12}{4}\), which simplifies to \(u = 3\).

Answer:

\(u = 3\)
