15:24 is divisible by 3, simplifying it down to 3:8. 19:24, 7:8, and 6:8 are all obviously larger than this ratio, and 1:2 can be equalized to 4:8, which is also bigger than 3:8, so none of the answer choices are less than 15:24.
        
                    
             
        
        
        
For the answer to the question above,  the power of "y" doesn't influence descending order for x even if it is higher than power of x.
Unordered polynomial is 
7x3y3 + 4 - 11x5y2 - 3x2y
Polynomial in descending order  looks like this
-11x5y2 + 7x3y3 - 3x2y + 4
Degree of the second term is 5 ( because of x5 ) 
        
                    
             
        
        
        
{ y = 3 x - 4
  9x -3y = 14
Subsititute y = 3x-4 :
[ 9 x - 3 ( 3 x-14 )=14]
Refine:
9 x  - 3 ( 3 x - 4 ) = 14
- 2 = 0
is false , therefore the system of equations has no solution
Answer A
