I am having trouble figuring this out.

(r - 6s + 3) + (7r + 5s) + (s+5)

• algebra -

Clear the parentheses.
r-6s+3+7r+5s+s+5=??
combine like terms.

• algebra -

I rewrite it according to terms.

r+7r= 8r which is like saying 1+7=8 (then add back the variable)
Same applies to the following:

-6s+5s+s=0 which is like saying -6+5+1=0

3+0+5= 8

So you would end up with: 8r+8
