# Solve 2|x+1|-2x=|2x-1|+1

Dear chilikuri

cse 1 x<-1

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

2-(x+1)-2x=-2x+1+1

2-(x+1)=21

so x=-2

case 2  -1≤x<0

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

2(x+1)-2x=-2x+1+1

x=0

but it is not a solution because x=0 is not lie in -1≤x<0

case 3     0≤x

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

2(x+1)-2x=2x-1+1

2(x+1)=2(x+1)

which is always true so x≥0 is its solution
