1. $101+(105:x-12).7=122$

   $(105:x-12).7=122-101$
   $(105:x-12).7=21$

   $105:x-12=21:7$
   $105:x-12=3$

   $105:x=3+12$
   $105:x=15$

   $x=105:15$

   $x=7$
   Vậy $x=7$

   $———$

   $144:(8.x-76)=36$

   $8.x-76=144:36$

   $8.x-76=4$

   $8.x=4+76$
   $8.x=80$
   $x=80:8$

   $x=10$
   Vậy $x=10$
