Решите уравнение: а) 9 16/51 - с = 4 11/34 б) а - 5 2/15 = 3 5/12

9 16/51 - с = 4 11/34

с = 9 16/51 - 4 11/34 = 9 32/102 - 4 33/102

х = 4 101/102

проверим:

9 16/51 - 4 101/102 = 4 11/34

9 32/102 - 4 101/102 = 4 11/34

(950 - 509) / 102 = 4 11/34

441/102 = 4 11/34

147/34 = 4 11/34

4 11/34 = 4 11/34

а - 5 2/15 = 3 5/12

а = 3 5/12 + 5 2/15 = 3 25/60 + 5 8/60 = 8 33/60

а = 8 11/20

проверим:

8 11/20 - 5 2/15 = 3 5/12

8 33/60 - 5 8/60 = 3 5/12

3 25/60 = 3 5/12

3 5/12 = 3 5/12

A) c=9 16/51-4 11/34=9 32/102-4 33/102=8 134/102-4 33/102=4 101/102

b) a=5 2/15+3 5/12=5 8/60+3 25/60=8 33/60=8 11/20
