Writing together,
===> x+x-1+x-(x+1)+x+x-(x-1)
===> x+x-1+x-x+1+x+x-x+1
===>3x+1
===> x+x-1+x-(x+1)+x+x-(x-1)
===> x+x-1+x-x+1+x+x-x+1
===>3x+1

= {x +(x-1)} + {x- (x-1)} + [x+ {x - (x - 1)}]
= { 2x - 1 } + {1} + [ x+1]
= { 2x - 1 +1 +x +1 }
= 3x + 1
= { 2x - 1 } + {1} + [ x+1]
= { 2x - 1 +1 +x +1 }
= 3x + 1
I hope my solution will help you.
