Ответ:
18\30 - Х = 4\30 + 6\30
18\30 - х = 10\30
18\30 - 10\30
8\30
18\30 - 8\30 = 10\30
(13\67 + 6\67 ) - Х = 9\67
19\67 - Х = 9\67
19\67 - 9\67
10\67
(13\67 + 6\67 ) - 10 \ 67 = 9\67
10/15+(5/15-х)=14/15
5/15-х=14/15-10/15
5/15-х=4/15
Х=5/15-4/15
34/60+8/60+y=41/60+16/60
42/60+y=57/60
y=57/60-42/60
y=15/60
64/70 - х + 26/70 = 5/70
64/70 - х = 5/70 - 26/70
64/70 - х = - 21/70
х = 64/70 - (- 21/70)
х = 85/70
х + 27\46 = 35 \ 46 + 2\46
х + 27\46 = 37\46
37\46 - 27 \ 46 =
10\46
10\46 + 27\46 = 35 \ 46 + 2\46
