x=3
x=2

Explanation:

2/(3x)+2/3=8/(x+6)
or
2/3(1/x+1)=8/(x+6)
or
1/x+1=8/(x+6)(3/2)
or
1/x+1=12/(x+6)
or
1/x=12/(x+6)-1
or
12/(x+6)-1/x=1
or
(12x-x-6)/(x(x+6))=1
or
11x-6=x(x+6)
or
11x-6=x^2+6x
or
x^2-5x+6=0
or
x^2-3x-2x+6=0
or
x(x-3)-2(x-3)=0
or
(x-3)(x-2)=0
or
x-3=0
x=3----------------Ans 1
or
x-2=0
or
x=2----------------Ans 2
