  1. $|x+\dfrac{1}{6}|-\dfrac{3}{5}=0,7$
    $->|x+\dfrac{1}{6}|=\dfrac{7}{10}+\dfrac{3}{5}$
    $->|x+\dfrac{1}{6}|=\dfrac{13}{10}$
    $->$ \(\left[ \begin{array}{l}x+\dfrac{1}{6}=\dfrac{13}{10}\\x+\dfrac{1}{6}=-\dfrac{13}{10}\end{array} \right.\)
    $->$ \(\left[ \begin{array}{l}x=\dfrac{17}{15}\\x=-\dfrac{22}{5}\end{array} \right.\) 
    Chúc bạn học tốt !!!!!!!
