Answer:
1. {5,-9}
2.{4}
3.{9/2}
Step-by-step explanation:
The equation  can be solved as follows:
 can be solved as follows:




Then, the solutions of the equation are  .
.
Now, if  , we can solve the equation
, we can solve the equation  as follows:
 as follows:




So, the unique solution of this last equation is 
The last equation is  , where
, where  . To solve this equation we can proceed as follows:
. To solve this equation we can proceed as follows:







But, x=11/4 is not a solution of this equation. So the unique solution is x=9/2.
 
        
             
        
        
        
It should be one hundred twenty six (126) if my math is correct
        
                    
             
        
        
        
(60(100-5)/100)(100+5)/100
