We mathematically express the given such that it becomes,
            4 / (x - 4) = x / (x - 4) - 4/3
To answer this, multiply the equation by 3(x - 4) since this is the least common multiple (LCM). 
     
             4(3) = (3)(x) - 4(x - 4)
Simplifying,
             12 = 3x - 4x + 16
             4 = -4x
The value of x should be equal to -1.  
The calculated value of y can be calculated.  
        
             
        
        
        
Formula for volume of cylinder is area of base time height 
area of base equal pir^2 =3,14*(2,5)^2 = 3,14 *6,25 = 19,625 inches squared
V=area time height
170 = 19,625 *h
h = 170/19,625 = 8,662 inches
        
                    
             
        
        
        
X =  10 * 3^n
