To solve for \( c \) in the equation \( 42c - 5 = 7 \), follow these steps:

1. Start with the original equation:
\[
42c - 5 = 7
\]

2. Add 5 to both sides to isolate the term with \( c \):
\[
42c = 7 + 5
\]
\[
42c = 12
\]

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

4. Simplify the fraction:
\[
c = \frac{2}{7}
\]

Now, we can convert \( \frac{2}{7} \) to decimal form:
\[
c \approx 0.2857
\]

None of the options given (6.7, 8, 12.6, 11) match the solution \( \frac{2}{7} \) or its decimal equivalent approximately 0.2857.

Please double-check the options as the answer computed does not correspond to any provided responses.
