    $($ 1/2/3 $-$ $2x$ $)$ $.$ $($ $x$ $+$ $\dfrac{1}{2}$ $)$ $=$ $0$
    $⇒$ $($ 1/2/3 $-$ $2x$ $)$ $=$ $0$ và $\dfrac{1}{2}$ $)$ $=$ $0$
    $⇒$ $2x$ $=$ 1/2/3 và $x$ $=$ $\dfrac{1}{2}$
    $⇒$ $x$ $=$ 1/2/3 $:$ $2$ và $x$ $=$ $\dfrac{1}{2}$
    $⇒$ $x$ $=$ $\dfrac{1}{12}$ và $x$ $=$ $\dfrac{1}{2}$
