Verified answer

(5 1/6 - х) : 14/29 - 1 3/14= 3 2/7  

 (5 1/6 - х) : 14/29 = 1 3/14 + 3 2/7  

 (5 1/6 - х) : 14/29 = 4 1/2

(5 1/6 - х) = 4 1/2 * 14/29

 (5 1/6 - х)  = 63/29

 х=5 1/6-63/29

х= 2 173/174

  (2,375 * 4/3 - 2 5/9) / (7,125 - 157,8 * 1/24 )  =

(3 2/3 - 2 5/9) / ( 7,125 - 6,575 ) = (1 1/9) / (0,55) = 2 2/99

 (28,8 * 7/96 + 6,6 * 3/2) / (1 11/16 * 4/9 )= 

 (2,1 + 9,9) / ( 3/4 ) = 12 * 4 / 3 = 16
