First step
You must stablish a relation  
150 ml sauce/100 ml vinegar
If   100 ml vinegar_______150ml sauce  then  11 ml vinegar ____x ml sauce
Second step
You must resolve x from the equation  
X= (11ml vinegar*150 ml soya)/(100 ml vinegar)= 16.5 ml sauce, it means that it will be  16,5 ml sauce by every 11 ml  of vinegar
 
        
                    
             
        
        
        
  13 units from 20 could either be 33 or 7; 15 units from -8 could either be 7 or 23.Since 7 satisfy both of the above requirements, Sarah's favorite number is 7. (You could show your work using a number line)
 
  The two possibilities of Neil's favorite number are 26 and -12.
        
                    
             
        
        
        
8k-4k+4+7-k = 
8k-4k-k+4+7 = 
3k+11
