РЕШИТЕ УРАВНЕНИЯ НЕ КАК В Г*Д*З И СО ОБЪЯСНЕНИЯМИ

Пошаговое объяснение:

7 7/30 - (5 11/30 - y ) = 3 19/30

7 7/30 - 5 11/30 + y = 3 19/30

1 26/30 + y = 3 19/30

y = 3 19/30 - 1 26/30

y = 1 23/30

19 28/34 - ( m + 2 29/34) = 12 15/34

19 28/34 - m - 2 29/34 = 12 15/34

16 33/34 - m = 12 15/34

m = 16 33/34 - 12 15/34

m = 4 18/34

m = 4 9/17

(x - 1 9/17) + 2 14/17 = 5 5/17

x - 1 9/17 + 2 14/17 = 5 5/17

x + 1 5/17 = 5 5/17

x = 5 5/17 - 1 5/17

x = 4

4 5/7 - (x - 6 3/7) = 2 6/7

4 5/7 - x + 6 3/7 = 2 6/7

10 8/7 - x = 2 6/7

x = 10 8/7 - 2 6/7

x = 8 2/7
