Okay suppose I want to solve this inequality for a graphic. Well first thing I want to do when solving inequality similar to solving an equation. Just try to get X by itself. So I’m going to try to move -2 X. to the other side. I’m subtracting two x opposite operation is adding adding two X. When I add two X. This is flipped my inequality I left with three X months nine. No it does not. When does my inequality flip? When I multiply or divide by a negative number? Okay I’m just adding and I’m gonna move nine to the other side. Subtracting nine. I’m gonna add nine. This also doesn’t flip my inequality…
