5 - (1 1/2v +1/3)*6 = 2 1/3v - 5 1/2

Question

5 - (1 1/2v +1/3)*6 = 2 1/3v - 5 1/2

Answer 1

5 - (1  1/2v +1/3)*6 = 2  1/3v - 5  1/2

5 - (3/2v +1/3)*6 = 7/3v - 5 1/2

5 - 9v - 2 = 2 1/3v - 5 1/2

9v + 2  1/3v  = 3 + 5  1/2

11 1/3v  = 8  1/2

34/3 v  = 17/2

v = 17/2 : 34/3

v = 3/4

Ответ. v = 3/4
