y=5 27/47+18 38/47=23 65/47=24 18/47
Verified answer
А) х = 23 4/29 - 6 17/29 = (22-6) + ((29+4)/29 - 17/29) = 16 + (33-17)/29 = 16 + 16/29 = 16 16/29х = 16 16/29
а можно другим способом:
х = 23 4/29 - 6 17/29 = 671/29 - 191/29 = 480/29 = 16 6/29
б) у = 8 15/128 - 6 12/128 = 1039/128 - 780/128 = 259/128 = 2 3/128
в) у = 5 27/47 +18 38/47 = 262/47 + 884/47 = 1146/47 = 24 18/47
