 \frac{3x  + 1}{x - 2}  - 10( \frac{x - 2}{3x + 1} ) = 3 \\  =>  \frac{3x  + 1}{x - 2}   - 10 \times \frac{x - 2}{3x + 1} = 3 \\  =  >  \frac{ {(3x + 1)}^{2}  - 10 \times  {(x - 2)}^{2} }{(x - 2)(3x + 1)}  = 3 \\  =  >  \frac{9 {x}^{2}  + 6x + 1 - 10( {x}^{2} - 4x + 4) }{3 {x}^{2} + x - 6x - 2 }  = 3 \\  =  >  \frac{9 {x}^{2} + 6x + 1 - 10 {x}^{2}   + 40x - 40}{3 {x}^{2} - 5x - 2 }  = 3 \\  =  >   -  {x}^{2} + 46x - 39 = 3(3  {x}^{2}  - 5x - 2) \\  =  >  -  {x}^{2}  + 46x - 39 = 9 {x}^{2} - 15x - 6 \\  =  >  -  {x}^{2}   - 9 {x}^{2}  + 46 x+ 15x - 39 + 6 = 0 \\  =  >  10 {x}^{2}  + 61x - 33 = 0 \\  =  > 10 {x}^{2}  - 61x + 33 = 0 \\

=> 10x^2 - 6x - 55x +33 = 0

=> 2x( 5x-3) - 11( 5x -3) =0

=> (2x-11)(5x-3)=0

so

2x-11=0

2x = 11

x = 11/2

or

5x-3=0

5x = 3

x = 5/3
