-- Posted by KRNsoccerplayer24 at 7:40 pm on Dec. 7, 2008 What would a number line look like with |5t+7|+8=17 I got not clue how to graph a number line for this. I KNOW i had a previous topic of the same stuff.  But there was a lot of confusion for me and i wanted to clear this up. Please only reply if you can help. -- Posted by matto at 7:42 pm on Dec. 7, 2008 |5t + 7| = 9 5t + 7 = 9 (t = 2/5) 5t + 7 = -9 (t = -16/5) so it'll be a dot over -16/5 and a dot over 2/5, since those are the only two values that satisfy the equation -- Posted by major at 7:44 pm on Dec. 7, 2008 |5t+7|+8=17   -8 -8 |5t+7|=9 from here it can be either 5t +7=9 5t=2 t=2/5 or 5t+7=-9 t=-16/5 it would just be those two points, unless you're doing an inequality
