Answer 2

To solve the equation \( -\frac{x}{2.9} = -3 \), you can start by eliminating the negative signs on both sides:

\[
\frac{x}{2.9} = 3
\]

Next, multiply both sides of the equation by \( 2.9 \) to isolate \( x \):

\[
x = 3 \times 2.9
\]

Now calculate the right side:

\[
x = 8.7
\]

So, the solution to the equation is:

\[
\boxed{8.7}
\]

Answer 3

To solve the equation \( \frac{8}{5}x = -10 \), we can start by isolating \( x \).

First, multiply both sides by \( \frac{5}{8} \) to get \( x \) alone:

\[
x = -10 \cdot \frac{5}{8}
\]

Now, calculate the right side:

\[
x = -\frac{50}{8}
\]

To simplify \( -\frac{50}{8} \), divide both the numerator and the denominator by 2:

\[
x = -\frac{25}{4}
\]

Thus, the solution is:

\[
\boxed{-\frac{25}{4}}
\]
