Answer:
-3s + 6
Explanation:
In order to find the answer you need to combine like terms. When you combine like terms you need to combine integers that have the same variable in this case 8 and 11 need to be combined due to the fact they both have the variable s.
8s - 11s + 6
(8s - 11s)
(8s - 11s) + 6
8s + -11s = -3s
= -3s + 6
