Simplify 67c − 59d − 12 c + 13d

To simplify \(67c - 59d - 12c + 13d\), we can combine like terms.

1. Combine the \(c\) terms:
\[
67c - 12c = 55c
\]

2. Combine the \(d\) terms:
\[
-59d + 13d = -46d
\]

So, the simplified expression is:
\[
55c - 46d
\]

This means none of the provided options are correct for the simplification. Let me know if you need any further assistance!

well all of the numbers next to eachother like (example 12) actually mean (example 1/2)

Thank you for the clarification! In that case, let's reinterpret your original expression considering the fractions.

Given:

\[
67c - 59d - \frac{12}{c} + \frac{13}{d}
\]

### Step 1: Rewrite the expression

First, we interpret the expression properly:

\[
67c - 59d - \frac{12}{c} + \frac{13}{d}
\]

### Step 2: Simplify

1. We combine the \(c\) terms and the \(d\) terms separately.

There are no like terms among the fractions, so we just have:
- For \(c\): \(67c - \frac{12}{c}\) (they can't be combined directly)
- For \(d\): \(-59d + \frac{13}{d}\) (similar situation)

Thus, the expression doesn't simplify further in this context.

If your intent was to find a common expression format or another fractional interpretation, please clarify further!
