Question

find X
|| X - 1|+2|=1​

Answer 1

Answer:

x is not exist

Step-by-step explanation:

let x>1 then modules will open positive

|x-1 +2| = 1

|x+1|=1

x+1 =1

x=0 before we assume x>1 then it is contradictory.

let x<1 then modules will open negetive

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

| -x+1+2 | = 1

so |-x+3| = 1

now, -x+3 = 1

x = 3-1 = 2

again it is contradiction..
