Пошаговое объяснение:
7 1/6-2 1/3х=2 2/3
7 1/6 - 2 2/3= 2 1/3х
43/6- 8/3 = 7/3х
(43- 16)/6 = 7/3х
27/6= 7/3х
х = 27/6 : 7/3
х= 27/6 * 3/7
х= 27/14
х= 1 13/14
х = 1 13/14
Пошаговое объяснение:
7 1/6 - 2 1/3х = 2 2/3
2 1/3х = 7 1/6 - 2 2/3
7/3х = 43/6 - 16/6
7/3х = 27/6
х = 27/6 : 7/3
х = 27/6 * 3/7
х = 27/14 = 1 13/14
7 1/6 - 7/3*27/14 = 7 1/6 - 9/2 = 7 1/6 - 4 1/2 = 6 7/6 - 4 3/6 = 2 4/6 = 2 2/3
