-6(2x - 4) =  -6*(2x) -6*(-4) = -12x + 24

-(12x - 6) + 18 = -12x + 6 + 18 =  -12x + 24

-3(4x - 3) + 15  = -3*(4x) -3*(-3) + 15 = -12x + 9 + 24 = -12x + 24

-4(3x + 6) = -4*(3x) -4*(6) = -12x -24

All the expressions gave the same answer as -12x + 24, except for the last expression.

So, -4(3x + 6)  is not equivalent to the others.
