(7/3-1/4х)*41/7=41/10
41/3-41/28х=41/10
5740-615х=1722
-615х=1722-5740
-615х=-4018
х=98/15
Пошаговое объяснение:
(2. 1/3 - 1/4х) * 5. 6/7 = 4,1
2. 1/3 - 1/4х = 4,1 : 5. 6/7
2. 1/3 - 1/4х = 41/10 : 41/7
2. 1/3 - 1/4х = 41/10 * 7/41
2. 1/3 - 1/4х = 7/10
1/4х = 2. 1/3 - 7/10
1/4х = 2. 10/30 - 21/30
1/4х = 1. 40/30 - 21/30
1/4х = 1. 19/30
х = 1. 19/30 : 1/4
х = 49/30 * 4/1
х = 49/15 * 2/1
х = 98/15
х = 6. 8/15
