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

You can put this solution on YOUR website! You have to use abs(3x+5) to get it to show absolute value.
Since there's only one variable, the solution is two points, so a number line showing the two points would be sufficient.
