-12c-12a+7a+6c=

To simplify the expression \(-12c - 12a + 7a + 6c\), you can combine like terms.

First, group the terms involving \(a\) and those involving \(c\):

• For \(a\): \(-12a + 7a = -5a\)

• For \(c\): \(-12c + 6c = -6c\)

Now, combine these results:

\[ -6c - 5a \]

So, the simplified expression is:

\(-6c - 5a\)
