We need to look at factors of 2, which are only 2 and 1... How do we get them to add to -3? Well, they have to be negative.
-2 + -1 = -3
What about the multiplication? A negative × a negative = a positive, so
-2 × -1 = 2
So your answer is 
-2 and -1
        
             
        
        
        
Answer: x=4 y=14 z=4
Step-by-step explanation:
On edge it is that 
 
        
             
        
        
        
X+y=155. Y= -x+155
1.50x +4(-x+155)= 520
1.50x-4x+620=520
-2.5x =-100
X= 40. Y=110
