Add -2 to both sides of the inequality 6 > 2. Then divide both sides of the inequality "-10 > -20 by -2. Explain in your own words what happens in both examples and when the direction of the inequality symbol is reversed

Let's start with 6>2
Add -2 to both sides:
6-2 > 2-2
4 > 0
Alright, now let's flip the sign like they asked:
4 < 0
Ok, now let's do the second part:
-10 > -20
Divide by -2
-10/-2 > -20/-2
5 > 10
Now flip the sign like they asked:
5 < 10
What you are supposed to gain from this is the realization that when you add or subtract, the equality remains unchanged and if you began with a true statement, you end with a true statement (without the need for changing the sign).
However, when you divide by a negative or multiply, you MUST flip the inequality sign. Pay attention to where I mark statements true or false before and after I operate on them.
Hope this helps.
Does this work for you? Are you understanding?
Yes, thank you so much! I have another one posting...
