Take a look at the diagram

On the right I am trying to show that 3 < 9

When you multiply or divide by -1 it becomes -9 < -3

Make up your own example. When you multiply or divide by a negative it has the effect of reflecting in the 'y axis' so the inequality flips around.

Hope that makes sense.

]]>This makes sense. With this rule though, I just must remember it, right? Does it exist for a reason? Or is it just one we must remember?

Thanks!!!!

]]>x by 5

Add 2z

take 6

divide by 2

I suspect you ran into difficulty because of this

take 2

divide by -2

when you multiply or divide by a negative amount you must reverse the inequality sign

If you want to explore this rule some more, post back.

hi bobbym, sorry didn't know you were posting too.

]]>Can you please show me your working?

]]>I am getting z > -2.

]]>Hope you all are doing good.

I have

(6/5) > (2/5) - (2/5)z

I get this down to z > 2.

The answer says it should be, z < 2.

Please help me? Thank you!!!!
