To solve the equation \( \frac{8}{5}x = -10 \), we need to isolate \( x \).
- Start by multiplying both sides of the equation by \( \frac{5}{8} \) to eliminate the fraction:
\[ x = -10 \times \frac{5}{8} \]
- Calculate the right side:
\[ x = -\frac{10 \times 5}{8} = -\frac{50}{8} \]
- Simplify \( -\frac{50}{8} \):
\[ x = -\frac{25}{4} \]
So, the solution to the equation is:
\[ \boxed{-\frac{25}{4}} \]
This corresponds to the response: − 25/4.
