Am I correct? −5−3(g+7)29/-4 g>−7.25

Hero:

Are you sure the original inequality is correct as written?

iosangel:

Yes

Hero:

Your work looks right but

Hero:

You flipped the sign before dividing by the negative which means you don't know exactly when to flip the sign which may become a problem later if it is not addressed right now. From the fact that you avoided using the method I showed you, it is clear that you do not prefer the method. But it is the method to use to avoid the mistake if you do it properly. Is your final answer correct, yes, but some of your steps are not exactly correct.

Hero:

The best method to use is the one that avoids flipping the signs. You won't realize it until later though.

iosangel:

Ok Yea your method was a bit hard soi used another method thank you though

Hero:

It wasn't hard at all. It's the same method. It just avoids the unncessary flipping of signs.

iosangel:

was it idk

Hero:

Explain what was so hard about it?

Hero:

You didn't do anything different than you did here.

iosangel:

The part in the end where you flip the signs

Hero:

With my method, you don't need to flip the sign.

Hero:

All you do is add subtract, multiply or divide

iosangel:

I think you need to flip the sign if there is a negitive idk

Hero:

If you multiply or divide negatives you need to flip a sign.

Hero:

But with my approach, you avoid multiplying or dividing negatives and thus avoid flipping signs.

iosangel:

Ok
