Solve for $u$. \[ \frac{u}{2} \leq 3 \] Submit

Step 1 ：Multiply both sides of the inequality by 2: \(2*\frac{u}{2} \leq 2*3\)

Step 2 ：This simplifies to: \(u \leq 6\)

Step 3 ：Check the solution by substituting a value for \(u\) that is less than or equal to 6 into the original inequality. For example, if we let \(u = 4\), we get \(\frac{4}{2} \leq 3\), which simplifies to \(2 \leq 3\). Since this is true, our solution is correct.

Step 4 ：Final Answer: \(\boxed{u \leq 6}\)
