Equation 1 ==> y - x = -13 
Equation 2 ==> -4x + 3y = -51 
3(y - x) = 3(-13) 
Equation 3 ==> 3y - 3x = -39 
Equation 2 - 3 
= (3y - 3y) + ( -4x - (-3x) ) = -51 - (-39) 
-x = -12 
x = 12 
Substitude x into equation 1 
y - 12 = -13 
y = -1
        
             
        
        
        
Answer:
the volume of the sphere is 

Step-by-step explanation:
This problem bothers on the mensuration of solid shapes, sphere and cube.
Given data
Volume of cube v =   64 cubic inches
since we are dealing with a cube the height and the radius of the sphere is same as the sides of the cube,
we know that volume of cube is expressed as
 


![l= \sqrt[3]{64}](https://tex.z-dn.net/?f=l%3D%20%5Csqrt%5B3%5D%7B64%7D)

also diameter d=length l
Diameter d=   
 
Radius r =   =
=  =
= 
Height h=
we know that the volume of a sphere is given by

substituting into the formula we have

 
        
             
        
        
        
The answer is C hope it helped
