Question

|x+1/2|=-4/3

Answer 1

=>\(x\in\varnothing\)

Answer 2

\(|x+\dfrac{1}{2}|=-\dfrac{4}{3}\)

\(|x+\dfrac{1}{2}|=-\dfrac{4}{3}\) \(\ge\text{ 0 ∀ x}\)

\(\Rightarrow\text{​​}\text{​​}|x+\dfrac{1}{2}\ne-\dfrac{4}{3}\)

\(\Rightarrow\)  ko tồn tại \(x\) thỏa mãn yêu cầu đề bài.

Answer 3

vì \(\left|x+\dfrac{1}{2}\right|\ge0;\forall x\)

\(\Rightarrow\left|x+\dfrac{1}{2}\right|\ne-\dfrac{4}{3}\)

\(\Rightarrow x\in\varnothing\)
