Hi there! 
To solve this problem, we need to simplify. 
5x + 32 = 4 - 2x
7x + 32 = 4
7x = -28
x = -4
Hope this helps!
        
                    
             
        
        
        
It need to be more clear for me to read
        
             
        
        
        
The answer is (5+3)× 2-(6)=10
        
             
        
        
        
Use the midpoint formula 

 plug in points DF and ED to get (-3,0) and (0.5, 0)
 
        
        
        
The answer is 4 because nine less 8 no less that 3
