To solve the given expression, we need to simplify the addition of two fractions. Notice that the second fraction has a denominator that is the negative of the first fraction's denominator. This means we can rewrite the second fraction to have a common denominator with the first. After rewriting, we can add the fractions directly. Simplify the resulting expression if possible.
Step 1: Define the Fractions
We start with the expression:
\[
\frac{63m + 9}{7m - 6} + \frac{63}{6 - 7m}
\]
Notice that the second fraction can be rewritten as:
\[
\frac{63}{6 - 7m} = -\frac{63}{7m - 6}
\]
Thus, we can express the entire equation as:
\[
\frac{63m + 9}{7m - 6} - \frac{63}{7m - 6}
\]
Step 2: Combine the Fractions
Now that both fractions have a common denominator, we can combine them:
\[
\frac{(63m + 9) - 63}{7m - 6}
\]
This simplifies to:
\[
\frac{63m + 9 - 63}{7m - 6} = \frac{63m - 54}{7m - 6}
\]
Step 3: Simplify the Expression
Next, we can factor out the numerator:
\[
63m - 54 = 9(7m - 6)
\]
Thus, we have:
\[
\frac{9(7m - 6)}{7m - 6}
\]
Assuming \(7m - 6 \neq 0\), we can cancel the common terms:
\[
9
\]
Final Answer
The simplified result of the given expression is:
\[
\boxed{9}
\]
