х-9 3/7=6 5/14-5 8/21
х-9 3/7=6 15/42-5 16/42
х-9 3/7=5 57/42-5 16/42
х-9 3/7=41/42
х=41/42+9 3/7
х=41/42+9 18/42
х=9 59/42
х=10 17/42
Пошаговое объяснение:
х= 10 ¹⁷/₄₂
Пошаговое объяснение:
(x-9 3/7)+5 8/21=6 5/14
x-9 3/7+5 8/21=6 5/14
x = 9 3/7 - 5 8/21+ 6 5/14
х= 10 ¹⁷/₄₂
3/7 - 8/21+ 5/14 = 18/42-16/42 + 15/42 =17/42
