||x-1|-2|=|x-3|

Dear Student

Here in this we need to verify the result,using the definition of modulus function.

Let x1|x-1-2|=|x-3||x-3|=|x-3|verified,Now let if x3|x-1-2|=x-3x-3=x-3verified too.What we did here we checked it at the critical points.Hence, the answer is x1

Solve the mod bracket inside and then solve the result under the whole mod bracket
  • -1
