Answer:
x = 24.27385%
Step-by-step explanation:
We can say 96.4x=23.4
Divide by 96.4: (x=23.4/96.4) = 0.24273858921
x=0.24273858921 so x = 24.27385...%
 
        
             
        
        
        
The answer is x=20. You isolate the square root. Eliminate the radical on the left handside. And then solve it!
