Пошаговое объяснение:

1 )(829-х)+365=514

   829-х=514-365

   829-х=149

   х=829-149

   х=680

  (829-х)+365=514

2) 406+(a-325)=901

   а-325=901-406

   а-325=495

   а=495+325

   а=820

3) b×18+312=402

   b*18=402-312

   b*18=90

   b=90:18

   b=5

4) 800-c÷6=786

   с:6=800-786

   с:6=14

   с=14*6

   с=84

   800 - 84÷6=786
