Question

/ x + 3 phần 4 /- 1 phần 2=0

Answer 1

\(\left|x+\frac{3}{4}\right|-\frac{1}{2}=0\)

\(\Rightarrow\left|x+\frac{3}{4}\right|=\frac{1}{2}\)

\(\Rightarrow x+\frac{3}{4}=\pm\frac{1}{2}\)

+) \(x+\frac{3}{4}=\frac{1}{2}\Rightarrow x=\frac{-1}{4}\)

+) \(x+\frac{3}{4}=\frac{-1}{2}\Rightarrow x=\frac{-5}{4}\)

Vậy \(x=\frac{-1}{4}\) hoặc \(x=\frac{-5}{4}\)
