The bisected  angle sets up  the following relationship  :

 

(6x)/ (7x)  =  (9x)  /( 11x - 4)     cross-multiply

 

6x ( 11x  - 4)  = 9x * 7x

 

66x^2 - 24x  =  63x^2

 

66x^2  - 63x^2  =  24x

 

3x^2 - 24x  = 0

 

3x  ( x - 8)  =  0

 

The second factor  set to 0  is what we need

 

x -  8  =  0

 

x = 8
