Best ResponseYou've already chosen the best response.1\[3s \ge 18\] Divide both sides by 3 (so flip inequality): \[s\le 6\] He needs to remember to flip the inequality sign whenever he multiplies/divides by a negative number.

Best ResponseYou've already chosen the best response.0s has to be smaller than 6. like 7 is smaller than 6. Rest is correct.

Best ResponseYou've already chosen the best response.1@cgliss if you want to explain to him why this happens, give him the example of 1<5. If you multiply both sides by 1 without swapping the inequality sign around, you get 1<5. This doesn't make sense, so you have to flip it to 1>5.
