If we multiply the first equation by 2 we get
2x - 4y = 12
but the second equation is
2x - 4y = 10
2x - 4y can't have 2 different values  so the are no solutions 
        
                    
             
        
        
        
ANSWER
The correct answer is D.
EXPLANATION
If we express the monomial,

as product of primes, we obtain:

If we express the monomial 

as product of primes we obtain:

The least common multiple of these two binomials is the product of the highest powers of the common factors.
The LCM is 


Therefore the correct answer is D.
