I am having trouble figuring this out.
(r - 6s + 3) + (7r + 5s) + (s+5)
Clear the parentheses.
combine like terms.
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
So you would end up with: 8r+8
