To simplify the given expression $(3 - 5i) - (-1 + 8i)$, follow these steps:

1. Distribute the negative sign across the second complex number: $(3 - 5i) - (-1 + 8i) = (3 - 5i) + (1 - 8i)$

2. Combine the real parts and the imaginary parts:

   • Real parts: $3 + 1 = 4$
   • Imaginary parts: $-5i - 8i = -13i$

Thus, the simplified expression is: $4 - 13i$

So, the values for the placeholders are:

• Real part: $4$
• Imaginary part: $-13$
