tìm x biết :

3/5+|x-1/2|=3/2

nhanh hộ mink nha

 

Answer 1

\(\frac{3}{5}+\left|x-\frac{1}{2}\right|=\frac{3}{2}\Rightarrow\left|x-\frac{1}{2}\right|=\)\(\frac{9}{10}\)

\(\Rightarrow\orbr{\begin{cases}x-\frac{1}{2}=\frac{-9}{10}\\x-\frac{1}{2}=\frac{9}{10}\end{cases}}\)\(\Rightarrow\orbr{\begin{cases}x=\frac{-2}{5}\\x=\frac{7}{5}\end{cases}}\)

Vậy \(x=\frac{-2}{5}\)hoặc \(x=\frac{7}{5}\)
