  1. Giải đáp:
    Bạn tham khảo đáp án bên dưới nhé!
    Lời giải và giải thích chi tiết:
    $2x-|x+1|=\dfrac12\\\Rightarrow|x+1|=2x-\dfrac12\\\Rightarrow\left[ \begin{array}{l}x+1=2x-\dfrac12\\x+1=-\left(2x-\dfrac12\right)\end{array} \right.\\\Rightarrow\left[ \begin{array}{l}x=\dfrac32\\x=\dfrac{-1}{6}\end{array} \right.$
