  3(x+2)+2(x+3)=3x+6+2x+6=3x+2x+6+6=5x+12 
 

 2(x+4)+3(x+1) = 2x+8+3x+3
  =5x+11



  

 5(x+1)+4(x+2) = 5x+5+4x+8
  =9x+13



 

 2(x−1)+3(x+2) = 2x−2+3x+6
  =5x+4



 

 3(2x+3)+2(x−4) = 6x+9+2x−8
  =8x+1



 

 2(4x−3)+3(−x+2) = 8x−6−3x+6
  =5x



 

 4(5x+2)−2(3x+2) = 20x+8−6x−4
  =14x+4



 

 3(2x−5)−4(x−4) = 6x−15−4x+16
  =2x+1



 

 5(x−1)−2(−2x+1) = 5x−5+4x−2
  =9x−7



   

  (4x−6)+ (9x+3) = 2x−3+3x+1
  =5x−2



  
10
  (6x+3)− (4x−12) = 4x+2−x+3
  =3x+5
