Answer: 
X= - 44 
18x+3x+4-5=5(4x9
Collect like terms 
21x+4-5=5(4x-9
More variable to the left hand side and change its sign
21x-20x-1=-45
Correct like terms 
X=-45+1 
Which is x=-44
        
             
        
        
        
Step-by-step explanation:
No. of banana    Cost      Unit price
4                            2             0.50
6                            3              0.50
7                            3.5            0.50
20                          10            0.50
20                          10             0.50
33                          16.50        0.50
Cost = No of banana x unit price
Cost = 4 x 0.50 = 2
Cost = 6 x 0.50 = 3
Cost = 7 x 0.50 = 3.50
Cost = 20 x 0.50 = 10
No of banana = Cost / Unit price
No of banana = 10 / 0.50 = 20
No of banana = 16.50 / 0.50 = 33
 
        
             
        
        
        
The scale factor applied to the model is 8000. 8000 times one equals 8000
