Find all real numbers s such that -2(s - 7) > 4s + 8. Give your answer as an interval.
-2(s - 7) > 4s + 8 simplify the left side
-2s + 14 > 4s + 8 add 2s to both sides, subtract 8 from both sides
6 > 6s divide both sides by 6
1 > s which means the same thing as s < 1
So....the answer is ( - infinity, 1 )
