    8x - 4y = -5 <- this one isn't it, the slope is different 2x + y = -6 (*2) 4x + 2y = -12 ^ this one looks exactly the same like the one in the problem statement it has a different solution even though it has the same amounts of y, x that means there's a contradiction and the system is inconsistent
