Đáp án: $x = - \frac{{13}}{6}$
Giải thích các bước giải:
$\begin{gathered} 2(x - \frac{1}{2}) - 5(x + \frac{3}{5}) = - x + \frac{1}{3} \hfill \\ \Leftrightarrow (2x - 1) - (5x + 3) = - x + \frac{1}{3} \hfill \\\Leftrightarrow 2x - 1 - 5x - 3 + x - \frac{1}{3} = 0 \hfill \\ \Leftrightarrow - 2x - \frac{{13}}{3} = 0 \hfill \\ \Leftrightarrow 2x = - \frac{{13}}{3} \hfill \\ \Leftrightarrow x = - \frac{{13}}{6} \hfill \\ \end{gathered} $
