Question

solve for u.
\\(\frac{u}{3} - 4 = -7\\)
simplify your answer as much as possible.
\\(u = \square\\)

Explanation:

Step1: Add 4 to both sides

To isolate the term with \( u \), we add 4 to both sides of the equation \(\frac{u}{3}-4 = -7\). This gives us \(\frac{u}{3}-4 + 4=-7 + 4\), which simplifies to \(\frac{u}{3}=-3\).

Step2: Multiply both sides by 3

To solve for \( u \), we multiply both sides of the equation \(\frac{u}{3}=-3\) by 3. So, \(3\times\frac{u}{3}=3\times(-3)\), which simplifies to \(u = -9\).

Answer:

\( u=-9 \)
