C. 
you can tell because the if you subtract 4y from each side the equation will not make sense,
(5 does not equal -6)
basically if the same variable is on the other side its no solution.

Alright, thanks a lot. :)

haseeb96 · Answer

yes the answer is C ...
because when variable cancel then remaning value is 
5 = -6 
5 never equal to -6 
ttherefore you cannot solve this equation
