Alright, I suck at this type of stuff. Any help?

3. -6<x + 3<6
4. -3x > -6 or x - 5 < 2
5. x - 2 > 2x + 1 or 10 > -2x + 2

Do any of those Greater then or less than signs have a bar under them? _

5. x - 2 > 2x + 1 or 10 > -2x + 2

Its been 5 years since I've done this stuff, I'mma work on them over lunch. Hopefully it'll come back to me.

Do you have the answers in the back of your book, I have an idea of how it is done, but I think I am mixing it in with college algebra.

This is annoyingly basic, so I won't tell you the answer (it's probably in the back of the book anyway), only tell you how to solve these. This kind of stuff should be learnt.

[3.] Subtract 3 from each element.

[4.] Divide the first inequality by -3 and add 5 to the second one.

[5.] Subtract (x+1) from the first inequality. Divide the second one by -2 and add 1.

[6.] X^2 = X+X+X+X+X... X times.
D(X^2) = 2X.
D(X+X+X+X...) = 1+1+1+1...=X.
FInd the error.

Don't forget that whenever you multiply/devide and inequality by a negative you flip the symbol.

If he has neither learnt nor read that, what's he trying to get help from us for when he can't do either?

You might want to restate that more coherantly, because I have no idea what you are trying to say.

You misspelled/misspelt "coherently", so I couldn't understand your post.

Back on topic, I'm curious *why* GoldEagle is asking this here instead of asking his parents, his teacher, or looking it up in his textbook, or on a serious internet resource. If he couldn't get information out of them, what's going to work better about asking strangers on Teh Intarweb?

That's weird, I only needed #3...meh, sorry. Mods may close.
