How would you like us to HELP you?
I think that the first one is -1, the second one is g>-90, and the third one is n-2>6; n>8.
I'm just confused about how to solve these kind of problems.
Please help me!!

right on first, but second, when you multipy both sides by -5, the inequality reverses direction. On the third, you are correct.
