It will be 1.104 so i think it will be that ikd
        
             
        
        
        
To solve this, you need to do 1,266-451. that equals 815. then, divide 815 by 19. you should get 43. hope that helps.
        
             
        
        
        
The equation would be x+5*-2=6.
The result of that equation would be x=16
