Answer 1

To solve the equation $-\frac{x}{42.9}=-3$, you can follow these steps:

1. Multiply both sides by $-1$ to eliminate the negative sign: $$\frac{x}{42.9}=3$$

2. Multiply both sides by $42.9$ to isolate $x$: $$x=3\times 42.9$$

3. Calculate $3\times 42.9$: $$x=128.7$$

Thus, $x=128.7$.

However, the final answers provided do not contain $128.7$, so let's check the solution more closely.

It seems there's possibly a miscommunication in the given equation. If the equation was intended as $-\frac{x}{42.9}=-3$:

1. Eliminate the negatives: $$\frac{x}{42.9}=3$$

2. Multiply both sides by $42.9$: $$x=3\times 42.9=128.7$$

The provided options evaluate as follows:

• $-8.7$
• $-87$
• $8.7$
• $87$

None of these match with $128.7$. Given these results appear erroneous according to standard calculations, please verify the original equation or options available. The solution calculated is indeed $x=128.7$.
