  1. (-7)/12-2/3:x=(-5)/8     
    =>2/3:x=(-7)/12-((-5)/8)           
    =>2/3:x=1/24                       
    =>x=2/3:1/24                     
    =>x=2/3. 24                    
    =>x=16          
    vậy x=16              

  2. $-$$\dfrac{7}{12}$$-$$\dfrac{2}{3}$$:x=-$$\dfrac{5}{8}$
                  $\dfrac{2}{3}$$:x=-$$\dfrac{7}{12}$$-(-$$\dfrac{5}{8}$$)$
                  $\dfrac{2}{3}$$:x=$$\dfrac{1}{24}$
                        $x=$$\dfrac{2}{3}$$:$$\dfrac{1}{24}$
                        $x=$$\dfrac{2}{3}$$.$$\dfrac{24}{1}$
                        $x=16$
