           2 . |3/4 – x| = 7/12
    =>       |3/4 – x| = 7/12 : 2 
    =>       |3/4 – x| = 7/24
    => \(\left[ \begin{array}{l}\frac{3}{4} – x = \frac{7}{24}\\\frac{3}{4} – x = \frac{-7}{24} \end{array} \right.\)
    => \(\left[ \begin{array}{l}x = \frac{3}{4} – \frac{7}{24} \\x = \frac{3}{4} – \frac{-7}{24}\end{array} \right.\) => \(\left[ \begin{array}{l}x = 11/24\\x = \frac{25}{24} \end{array} \right.\)  
    Vậy x = 11/24 hoặc x = 25/24

    2. |3/4 – x| = 7/12
    <=> |3/4 – x| = 7/24
    <=> \(\left[ \begin{array}{l}\frac{3}{4} – x = \frac{7}{24}\\\frac{3}{4} – x = – \frac{7}{24}\end{array} \right.\) 
    <=> \(\left[ \begin{array}{l}x = \frac{11}{24}\\x= \frac{25}{24}\end{array} \right.\) 
    Vậy…
