Ответ:
5/6
Пошаговое объяснение:
1/6(4а - 2) - 1/5(5в + 6) =
4/6а - 2/6 - 5/5в - 6/5 =
2/3а - 1/3 - в - 1 1/5 =
2/3а - 5/15 - в - 1 3/15 =
2/3а - в - 1 8/15
а = 2 1/4; в = 4/5
2/3а - в - 1 8/15 = 2/3 * 2 1/4 - 4/5 - 1 8/15 =
2/3 * 9/4 - 4/5 - 1 8/15 = 18/12 - 4/5 - 1 8/15 =
3/2 - 4/5 - 1 8/15 = 45/30 - 24/30 - 1 16/30 =
21/30 - 46/30 = 25/30 = 5/6
