Question

The product of two integers is -160 one of them is 20 find the other

Answer 1

let the other integer be x
then x × 20=-160
x=-160÷20
x=-8
therefore other integer=-8

Answer 2

let the two integer be x and y
   
x*y= -160  
            
let x be 20
          
than , we get  
= 20*y= -160
                  
y= -160/20  
                
y= -8  
 
therefore the another integer is -8
(20*-8= -160)
