2 1/2 :(1/2x+5/12) - 1 5/6 =2/3​

Answer 1

Ответ:      х = 1 1/6 .  

Пошаговое объяснение:

2 1/2 :(1/2x+5/12) - 1 5/6 =2/3​ ;

2 1/2 : (1/2x + 5/12) = 2/3 + 1 5/6 ;

2 1/2 : (1/2x + 5/12) = 2 1/2 ;

1/2x + 5/12 = 2 1/2 : 2 1/2 ;

1/2x + 5/12 = 1 ;

1/2 х = 1 - 5/12 ;

1/2 х = 7/12 ;

      х = 7/12 : 1/2 ;

      х = 1 1/6 .
