**Reiny**, Wednesday, January 18, 2012 at 10:30amhow about starting like this

|2x+1| = |x+2| +2

2x+1 = |x+2| +2 or -2x-1 = |x+2|+2

|x+2|= 2x -1 or |x+2| = -2x-3

now again.

x+2 = 2x-1 or -x-2 = 2x-1, where 2x+1>0 --> x>-1/2

x = 3 or x=-1/3

or

x+2= -2x-3 or -x-2 = -2x-3 , where -2x-3>0 -->x <-3/2

3x=-5 or x = -1

x = -5/3 or x = -1

so x = -1 does not satisfy the condition

x=3 , -1/3 , -5/3 are possible solutions

testing each one in the original showed me that -1/3 does not work, so

x = 3, x = -5/3
