Distribute the 3 across the -8 and -4c.

3(-8 - 4c) = 3(-8) + 3(-4c) = -24 - 12c

So, -24 - 12c is the simplified form.
you distribute the 3 to everything inside the parenthesis

3( - 8 - 4c) = -24-4c

-24 - 4c

then you move -4c to the "other side of the equal sign

-24 = 4c

divide by 4 on both sides (isolate the variable)

-24/4 = 4/4c 

- 6 = c

c = -6

hope this helps
