Let's solve the given expression step-by-step.

The expression is:

\[ 5 + 5(10 - 20) \]

1. First, solve the operation inside the parentheses:
\[ 10 - 20 = -10 \]

2. Next, multiply 5 by the result of the parentheses:
\[ 5 \times -10 = -50 \]

3. Finally, add the result to 5:
\[ 5 + (-50) = 5 - 50 = -45 \]

So, the value of the expression is:
\[ \boxed{-45} \]
