8 - 1,5 * (3х + 2) = 2/3 * (4 - 6х)
8 - 4,5х - 3 = 8/3 - 4х
- 4,5х + 4х = 2 2/3 - 8 + 3
- 0,5х = - 2 1/3
х = - 2 1/3 : (- 0,5)
х = - 7/3 : (- 1/2)
х = (- 7/3) * (- 2/1)
х = 14/3
х = 4 2/3
-----------------------------------
Проверка: 8 - 1,5 * (3 * 14/3 + 2) = 2/3 * (4 - 6 * 14/3)
8 - 1,5 * 16 = 2/3 * (- 24)
8 - 24 = - 48/3
- 16 = - 16
