Question 568353
y= |x+2|-|x+1|
--------------------
for x<-2
y= -(x+2) +(x+1)
= -x-2+x-1
-----------------------
for -2<x<-1
y=x+2+x+1
y=2x+3
------------------------

for x >-1
y=x+2-x-1
y=1
---------------------------

if i graph these 3 equations, i will get the same resulting graph.
does it mean the points on the resulting graph are the solutions?

Ans: Yes
