Multiply by (n-2)
n - 2(n-2)/3 = 2
Multiply by 3
3n - 2n + 4 = 6
n = 2

.Is it( n/n)-2-2/3=(2/n)-2 or (n/n-2) -2/3=2/(n-2)?In the first case,the given exp.1-2-2/3=2/n -2 =>-2/n=-2-1+2+2/3 =>-2/n=- 1/3 or n=6. In the second case ,solution is not possible.

n/n -2 -2/3 = 2/n -2
n/n -2/n = -2 +2+2/3
(n-2)/n = 2/3
n - 2 = 2/3n
n- 2/3n = 2
1/3n = 2
n= 6
