To solve the equation \(-8x = -0.56\), you need to isolate \(x\). You can do this by dividing both sides of the equation by \(-8\):
\[ x = \frac{-0.56}{-8} \]
This simplifies to:
\[ x = \frac{0.56}{8} \]
Now, calculate \(0.56 \div 8\):
\[ x = 0.07 \]
Therefore, the solution of the equation \(-8x = -0.56\) is
\[ x = 0.07. \]
