Solve just like equations. Just keep the inequality sign instead. I'll do one. You try the others and show us what you get.
-6w < 84
divide by -6 to get
w > -14
The reason you change direction is that multiplication/division by a negative value is just a short way of moving things to the other side:
-6w < 84
-6w+6w < 84+6w
0 < 84+6w
-84 < 6w
-14 < w
-6w < 84
W > 14
W < -14
W > -14
W < 14
5m > 45
m < 9
m < 9
m > -9
m < -9
