Hey Kristie
Quick lesson for you.
Order of operations first

Inside most parentheses first, distribute the 5 into c-4 and 3 into 5c-2.

Simplify the -20 with +15 and -6 with +4.

Parentheses again, distribute the -1 with 15c-2.

Simplify, 5c with -15c and -5 with +2.

Distribute the 9.

Anymore questions feel free to ask me.
