х = 1 1/7
Пошаговое объяснение:
8 2/15 - (х+3 5/14) : 5 5/8 = 7 1/3
(х + 3 5/14) : 5 5/8 = 8 2/15 - 7 1/3
(х+3 5/14) : 5 5/8 = 12/15
х + 3 5/14 = 4/5 * 45/8
х + 3 5/14 = 9/2 = 4 1/2
х = 4 1/2 - 3 5/14
х = 1 2/14 = 1 1/7
Проверим:
8 2/15 - (1 1/7+3 5/14) : 5 5/8=7 1/3
8 2/15 -4 1/2 : 5 5/8 =7 1/3
8 2/15 - 9/2*8/45 = 7 1/3
8 2/15 - 4/5 = 7 1/3
7 5/15 = 7 1/3
7 1/3 = 7 1/3
х = 1 1/7
