Let's simplify the given expression step by step:

\[
-\frac{14}{12} + 0.65 - \left( -\frac{7}{42} - 0.35 \right) - \frac{14}{12} + 0.65 - \left( -\frac{7}{42} - 0.35 \right)
\]

First, simplify \(-\frac{14}{12}\):

\[
-\frac{14}{12} = -\frac{7}{6}
\]

Next, simplify \(-\frac{7}{42}\):

\[
-\frac{7}{42} = -\frac{1}{6}
\]

Now, substitute these simplified fractions back into the expression:

\[
-\frac{7}{6} + 0.65 - \left( -\frac{1}{6} - 0.35 \right) - \frac{7}{6} + 0.65 - \left( -\frac{1}{6} - 0.35 \right)
\]

Simplify the terms inside the parentheses:

\[
-\frac{1}{6} - 0.35 = -\frac{1}{6} - \frac{35}{100} = -\frac{1}{6} - \frac{7}{20}
\]

To combine these fractions, find a common denominator. The least common multiple of 6 and 20 is 60:

\[
-\frac{1}{6} = -\frac{10}{60}
\]
\[
-\frac{7}{20} = -\frac{21}{60}
\]

Now, combine these fractions:

\[
-\frac{10}{60} - \frac{21}{60} = -\frac{31}{60}
\]

So, the term inside the parentheses simplifies to:

\[
-\left( -\frac{31}{60} \right) = \frac{31}{60}
\]

Now, substitute this back into the expression:

\[
-\frac{7}{6} + 0.65 + \frac{31}{60} - \frac{7}{6} + 0.65 + \frac{31}{60}
\]

Combine like terms. First, combine the \(-\frac{7}{6}\) terms:

\[
-\frac{7}{6} - \frac{7}{6} = -\frac{14}{6} = -\frac{7}{3}
\]

Next, combine the \(0.65\) terms:

\[
0.65 + 0.65 = 1.3
\]

Finally, combine the \(\frac{31}{60}\) terms:

\[
\frac{31}{60} + \frac{31}{60} = \frac{62}{60} = \frac{31}{30}
\]

Now, the expression is:

\[
-\frac{7}{3} + 1.3 + \frac{31}{30}
\]

Convert \(1.3\) to a fraction:

\[
1.3 = \frac{13}{10}
\]

Find a common denominator for \(-\frac{7}{3}\), \(\frac{13}{10}\), and \(\frac{31}{30}\). The least common multiple of 3, 10, and 30 is 30:

\[
-\frac{7}{3} = -\frac{70}{30}
\]
\[
\frac{13}{10} = \frac{39}{30}
\]
\[
\frac{31}{30} = \frac{31}{30}
\]

Now, combine these fractions:

\[
-\frac{70}{30} + \frac{39}{30} + \frac{31}{30} = -\frac{70}{30} + \frac{70}{30} = 0
\]

So, the simplified value of the expression is:

\[
0
\]
