The problem asks you to simplify the following expression:

\[
-\left( \frac{1 + 5i}{7} \right) + \frac{1 + i}{7}
\]
where \(i\) represents the imaginary unit.

### Step-by-step simplification:

1. First, distribute the negative sign across the first fraction:
   \[
   -\left( \frac{1 + 5i}{7} \right) = \frac{-1 - 5i}{7}
   \]
   
2. Now rewrite the entire expression:
   \[
   \frac{-1 - 5i}{7} + \frac{1 + i}{7}
   \]
   
3. Since both fractions have the same denominator, we can combine the numerators:
   \[
   \frac{-1 - 5i + 1 + i}{7} = \frac{(-1 + 1) + (-5i + i)}{7}
   \]
   
4. Simplify the numerators:
   \[
   0 - 4i = -4i
   \]
   
5. Now the expression becomes:
   \[
   \frac{-4i}{7}
   \]

This is the simplified form of the expression. Since the problem asks for the answer in the form \(a + bi\), we can write it as:

\[
0 - \frac{4i}{7}
\]
or simply:

\[
0 - \frac{4}{7}i
\]

Thus, the answer is:
\[
0 - \frac{4}{7}i
\]
