х= 7 4/7
Пошаговое объяснение:
(1/7+х)-3 3/7=4 2/7
1/7+х=4 2/7 + 3 3/7
1/7+х=7 5/7
х=7 5/7 - 1/7
(1/7 + 7 4/7)- 3 3/7 =4 2/7
7 5/7 - 3 3/7 = 4 2/7
4 2/7= 4 2/7
х= 7 4/7
Пошаговое объяснение:
(1/7+х)-3 3/7=4 2/7
1/7+х=4 2/7 + 3 3/7
1/7+х=7 5/7
х=7 5/7 - 1/7
х= 7 4/7
(1/7 + 7 4/7)- 3 3/7 =4 2/7
7 5/7 - 3 3/7 = 4 2/7
4 2/7= 4 2/7
