Great, glad to hear that!
These questions are all I need. Thanks a lot and I have a suggestion. It will be better if you write 2's better.

When do we have to think of the overlap and when can we just take all the regions that are valid?

Is that a particular problem that you are lost on? There are a few different set ups in this video.

@@Greenemath For example in 9 and 10, both questions are similar in style. In 9 you take everything, but for 10 you take the overlap.

@Jovan Rio Tjandra that goes back to the definition of absolute value. It's actually explained at the beginning of each problem. Where |u| > k then u k and then for the next one we have |u| greenemath.com/College_Algebra/44/Solving-Absolute-Value-Inequalities.html I have a video coming out soon (Saturday) where all the absolute value problems will be put together as one. You may want to watch that as you may fill in some gaps.
helped a lot thankyou!!!!

Why do you not flip the inequality when you are distributing negatives to absolute values?
@Greenemath
Жыл бұрын
You flip the direction of the inequality symbol when you multiply or divide both sides by a negative. Distributing a negative does not change the direction of the inequality symbol.
Thanks for the great video! I'd appreciate if you could answer a question: Why doesn't it work to use the interval method (as seen on problem 5) to solve |3x-2| - |-(x/3) +1| =0 ? I did it and the results would seem ok but none of them belongs to their respective intervals. Am I doing something wrong? I got 9/10 for the interval x

Graphing, if possible, takes away much of the mystery

It definitely helps on difficult problems.
How about arcsin(|x-1|-2x+3|-3)

I have no idea what you are trying to do. There isn't an equality symbol or inequality symbol. Also, you have two left absolute value bars and only one on the right.
