I'm not looking for answers. I'm just looking for someone to show me, step by step, how to solve these two College Algebra math problems. I usually ask on this section of OSBot for these specific questions and I end up learning fairly quickly with one simple example. I'm giving Likes for the people that can do this. ;p

 

The math problems are listed in the link below:

Here is a hint, for the first problem you can easily solve it by pluggin in the answers. For example, what happens if you plug in 3 for x? You get 2/0 on the left hand side. You can also just solve for x.

 

For the second one, an importand part of it is to understand the difference between "( )" and "[ ] "

or any combination of the two. Do you know what those mean?

Sorry man i use to be able to do this type of stuff like nothing, but i been out the game for like 2 months. That what happens when you hit summer

Yes absolute value. But do I use the distribute property even if it's absolute value?

You get Qs  18 and 19  done?

Yes, now I need #25 done.

No, that is not what i meant. " | | " means absolute value. In math, "( )" means non inclusive and "[ ]" means inclusive. For example, 

 

(4, 20] would mean that 4 is not included in the answer, but is the lower bound, and 20 is included in the answer, and is the upper bound. So at the value of 20, it would also hold true, but at 4 it would not hold true.

I see. Is there a way you can show how you solved this answer?

Well I am at work so I cant sit down and actually write it out and then reproduce it for you, I just solved it in my head tbh. :P

 

Like I said, all you need to do is solve for x in both situations. ^_^

Someone able to show how they did #25?

Just need #25 solved.
