Пошаговое объяснение:
Пусть х л бензина было в первой бочке, тогда (1104 - х) л - во второй. Уравнение:
х - (1/5)х = (1104 - х) - 3/7 · (1104 - х)
(4/5)х = 1104 - х - 3312/7 + (3/7)х
(4/5)х + х - (3/7)х = 1104 - 473 целых 1/7
(9/5)х - (3/7)х = 630 целых 6/7
(63/35)х - (15/35)х = 4416/7
(48/35)х = 4416/7
х = 4416/7 : 48/35
х = 4416/7 · 35/48
х = (92·5)/(1·1)
х = 460 (л) - было в первой бочке первоначально
1104 - 460 = 644 (л) - было во второй бочке первоначально
ответ: 460 л и 644 л.
Проверка:
1) 460 - 1/5 · 460 = 460 - 92 = 368 (л) - осталось в первой бочке;
2) 644 - 3/7 · 644 = 644 - 276 = 368 (л) - осталось во второй бочке;
3) 368 = 368 - стало поровну в каждой бочке.
