Question

\(\left|x-\dfrac{3}{4}\right|=\dfrac{1}{4}\)

Answer 1

\(\left|x-\dfrac{3}{4}\right|=\dfrac{1}{4}\)

\(x-\dfrac{3}{4}=\dfrac{1}{4}\) hoặc \(x-\dfrac{3}{4}=-\dfrac{1}{4}\)

*) \(x-\dfrac{3}{4}=\dfrac{1}{4}\)

\(x=\dfrac{1}{4}+\dfrac{3}{4}\)

\(x=1\)

*) \(x-\dfrac{3}{4}=-\dfrac{1}{4}\)

\(x=-\dfrac{1}{4}+\dfrac{3}{4}\)

\(x=\dfrac{1}{2}\)

Vậy \(x=\dfrac{1}{2};x=1\)

Answer 2

\(|x\) \(-\) \(\dfrac{3}{4}|\)=\(\dfrac{1}{4}\)

\(x-\dfrac{3}{4}=\dfrac{1}{4}\)

       \(x=\dfrac{1}{4}+\dfrac{3}{4}\)

       \(x=1\)

Vậy \(x=1\)
