Answer:
x = 10
Step-by-step explanation:
Since L is the midpoint
KL = LM
2x-3 = x+7
Subtract x from each side
 2x-3-x = x+7-x
x-3 = 7
Add 3 to each side
x-3+3 = 7+3
x = 10
 
        
                    
             
        
        
        
Do 81/3=27/3=9/3=3, So you see the answer is 3^<span>4, I don't know if that's the official way to solve it but it works.</span>
