Пошаговое объяснение:
5 - 9v - 2 = 2 1/3v - 5,5
3 - 9v = 2 1/3v - 5,5
2 1/3v + 9v = 3 + 5,5
11 1/3v = 8,5
v = 8,5 : 11 1/3
v = 85/10 : 34/3
v = 17/2 * 3/34
v = 3/4
v = 3/4
Пошаговое объяснение:
5 - (1 1/2v + 1/3) * 6 = 2 1/3v - 5 1/2
5 - (3/2v + 1/3) * 6 = 2 1/3v - 5 1/2
5 - 3/2v*6 - 1/3*6 = 2 1/3v - 5 1/2
5 - 9v - 2 = 2 1/3v - 5 1/2
-9v - 2 1/3v = -5 1/2 - 5 + 2
- 11 1/3v = -8 1/2
-34/3v = -17/2
v = -17/2 : (-34/3) = -17/2 * (-3/34)
v = 51/68 = 3/4
