Answer:
The father is 40 and the son is 4.
Step-by-step explanation:
40 + 5 = 45. 
4 +5=9. 
45 divided by 5 = 9
 
        
             
        
        
        
9*(x-1)=2x-7
First get rid of your parenthesis by distributing. 
9x-9=2x-7
Then all you have to do is isolate the variable
9x=2x+2
7x=2
so x= 2/7
        
             
        
        
        
1/6 of the people are not elderly or men
<h3>How to determine the proportion?</h3>
The given parameters are:
Men = 1/2
Elderly = 1/3

People = 1 - Men - Elderly
So, we have:
People = 1 - 1/2 - 1/3
Evaluate
People = 1/6
Hence, 1/6 of the people are not elderly or men
