-p+q+2(p+q)-p-q
-12z+4(z-9)+30+z

Okay..
-5(c + d) – 4d + 5c – d
Firstly, distribute the -5.
-5c – 5d – 4d + 5c – d
Now, add all like terms.
-10d
There is no c anymore because -5c and 5c cancel each other out.
You should know how to do the rest based on what I told you.

You should multiply through. I’ll do the first one as a sample:
-5(c+d)-4d+5c-d
Multiply the 5 through in this case:
-5c-5d-4d+5c-d
Then, group like terms to add:
-5c+5c-5d-4d-d
(-5c+5c)+(-5d-4d-d)
0+-10d
-10d
