The given expression is:

\[
20 - (-3) + (-49)
\]

To simplify this:

1. Subtracting a negative number is the same as adding its positive value:
   \[
   20 - (-3) = 20 + 3 = 23
   \]

2. Now, add \(-49\):
   \[
   23 + (-49) = 23 - 49 = -26
   \]

So, the final result is:

\[
20 - (-3) + (-49) = -26
\]
