Question

|x-1/3|=1

Answer 1

\(x-\dfrac{1}{3}=1\)

\(x=\dfrac{1}{3}+1\)

\(x=\dfrac{4}{3}\)

Answer 2

nếu \(\left|x-\dfrac{1}{3}\right|>0\) ta có:

\(x+\dfrac{1}{3}=1\)

\(x=1-\dfrac{1}{3}\)

\(x=\dfrac{2}{3}\)

nếu\(\left|x-\dfrac{1}{3}\right|< 0\) ta có:

\(-x-\dfrac{1}{3}=1\)

\(-x=1+\dfrac{1}{3}\)

\(-x=\dfrac{4}{3}\)

\(x=\dfrac{-4}{3}\)

Answer 3

\(\left|x-\dfrac{1}{3}\right|=1\)

\(=>x-\dfrac{1}{3}=1\) hoặc \(x-\dfrac{1}{3}=-1\)

\(=>x=\dfrac{4}{3}\) hoặc \(x=\dfrac{-2}{3}\)

Vậy ...
