я правильно решил уравнение
14 9/16 - х = 6 3/4 + 1 2/5
233/16 - х = 27/4 + 7/5
233/16 - х = 135/20 + 28/20
233/16 - х = 163/20
1165/80 - х = 652/80
х = 1165/80 - 652/80
х = 513/80
х = 6 33/80
14 9/16 - х = 6 3/4 + 1 2/5
233/16 - х = 27/4 + 7/5
233/16 - х = 135/20 + 28/20
233/16 - х = 163/20
1165/80 - х = 652/80
х = 1165/80 - 652/80
х = 513/80
х = 6 33/80
