Answer 1

(2x-1)+(5x-2)-(4x-9) / 4x-1+x-3-2x-22x+5x-4x-1-2-9 / 4x+x-2x-1-3-2
3x+12 / 3x-6

Answer 2

 (2x-1)+(5x-2)-(4x-9) / 4x-1+x-3-2x-2
   (2x-1)+(5x-2)-(4x-9)   
     4x-1+x-3-2x-2

   2x-1+5x-2-4x+9 =    2x+5x-4x+9-1-2    
   4x-1+x-3-2x-2        4x+x-2x-1-3-2

 2x+5x-4x+9-1-2 =  3x + 6  = 3(x + 2)
 4x+x-2x-1-3-2        3x - 6       3(x - 2)   

 x +2
 x - 2
