Answer:
The system of equations is:
         x + y = 15
            xy = 15
Step-by-step explanation:
solve the first for y and substitute in the second:
             y = 15-x
       x(15-x) = 15
      15x - x� = 15
 15x - x� - 15 = 0
-x� + 15x - 15 = 0
 x� - 15x + 15 = 0
 
        
                    
             
        
        
        

Since 5 is divisible by 10 and 5, we can factor out a 5 from both terms.
