To solve the equation \(\frac{2}{3}u = -\frac{6}{5}\), we will first isolate \(u\).
- Multiply both sides by the reciprocal of \(\frac{2}{3}\), which is \(\frac{3}{2}\):
\[ u = -\frac{6}{5} \times \frac{3}{2} \]
- Calculate the right side:
\[ u = -\frac{6 \times 3}{5 \times 2} = -\frac{18}{10} \]
- Simplify \(-\frac{18}{10}\):
\[ u = -\frac{9}{5} \]
Thus, the solution is:
\[ u = -\frac{9}{5} \]
