1. x over 7 - x = 12
2. x+2x over 6 - 3 =0
3. 7x - 1
-------- = 2-3x
4 ----------
5
4. x over 4 - 2x +1 over 6 = -2
5. 2(x+5) over 3 + x over 4 = 2 over 3
'over' means that its a fraction just so you know

Question 891697: Hi, me and my friends are having troubling graphing 4|3x+5|+2=10 for our summer Algebra II packet. (the format is just showing it as  )
**We solved it as |x|= -7/3, -1 (mini question, would you squiggly bracket {} for the final answer as in {-7/3, -1}, or just use the former one?)
When the problem asks that we graph it, is it a grid graph, or a number line graph? I tried grid graphing from this equation, if it makes any sense: (steps)
4|3x+5|+2=10
take away 2
4|3x+5|=8
divide front and last by 4 to cancel
|3x+5|=2
move 2 over to the other side
|3x+5|-2=0
My logic, is that now I have a vertex: (-5,-2)
I'm probably all sorts of wrong by now, so I don't think it'd matter if I explain any further. (it got reaaally confusing)
Can you explain and help us graph this? Thank you! 8)
+formatting is acting funny, apologies

Question 892208: Hi, I was wondering if you could please help me with an absolute value question please? I did the math and got -5 and 5 and it is an "or" line but they both equal the equation. The problem is |3x| > 15. I did this:
3x>15 Or 3x>-15
3x/3> 15/3 3x/3>-15/3
x>5 x> -5
The problem is that they both equal 15 & the problem is >15
