The real part of the given number is $3$ and its imaginary part is $- 5$.

#### Explanation:

The standard form of a complex number is $a + i b$.
Where $a$ is the real part and $b$ is the imaginary part.

Write the given complex number in the standard form
The standard form of $- 5 i + 3 = 3 - i 5 = 3 + i \left(- 5\right)$.

Therefore the real part of the given number is $3$ and its imaginary part is $- 5$.
