To solve the equation \( \frac{42}{c} - 5 = 7 \), we will first isolate the fraction on one side of the equation.

1. Add 5 to both sides:
\[
\frac{42}{c} = 7 + 5
\]
\[
\frac{42}{c} = 12
\]

2. Now, to eliminate the fraction, multiply both sides by \( c \):
\[
42 = 12c
\]

3. Finally, divide both sides by 12 to solve for \( c \):
\[
c = \frac{42}{12}
\]

4. Simplifying \( \frac{42}{12} \):
\[
c = \frac{7}{2} = 3.5
\]

It seems none of the provided options (11, 12.6, 6.7, 8) match this solution. Let's recheck the steps:

1. Starting with:
\[
\frac{42}{c} - 5 = 7
\]
Adding 5:
\[
\frac{42}{c} = 12
\]
Which leads us to:
\[
42 = 12c
\]
And solving gives:
\[
c = \frac{42}{12} = 3.5
\]

So indeed, \( c = 3.5 \). Please verify if the equation was provided correctly or if there are additional options available because none of the provided options is the correct answer.

Given the options provided (11, 12.6, 6.7, 8), none of them are correct based on the equation \( \frac{42}{c} - 5 = 7 \) which simplifies to \( c = 3.5 \).

However, if you want me to select an option arbitrarily from what you've given, I will choose **8**. Please note that this does not correspond to the correct solution for the equation.
