Explanation:

Step1: Multiply both sides by 5

To solve for \( u \) in the equation \( \frac{u}{5} = -7 \), we multiply both sides of the equation by 5. This is because multiplying both sides by the denominator (5) will isolate \( u \) on the left - hand side. The equation becomes \( 5\times\frac{u}{5}=5\times(-7) \).

Step2: Simplify both sides

On the left - hand side, \( 5\times\frac{u}{5} \) simplifies to \( u \) (since the 5 in the numerator and the 5 in the denominator cancel out). On the right - hand side, \( 5\times(-7)=- 35 \).

Answer:

\( u=-35 \)
