Given x ＜ - 2, simplify | - x | + | - x + 2 | - | - 2-x|
|-x|+|x+2|-|2-x|
=-x+（-x-2）-（2-x)
=-x-x-2-2+x
=-x-4
Simplification: | X-2 | + | 2x + 1 | - | X-5|
Classified discussion
one
x>=5
|x-2|+|2x+1|-|x-5|=x-2+2x+1-x+5=2x+4
two
x
When x > 5, simplify: [X-5] - [2x-13]
Is it a bracket or an absolute number
In brackets = x-5-2x + 13 = 8-x
If it's an absolute number five
