Something is not right here.

You say arc AB = -4x °, but the arc AB would not be measured in degrees.

Did you mean the central angle subtended by arc AB is -4x° ? That would make sense.

If so, then the central angle subtended by an arc is twice the angle subtended by the same arc at the circle.

then

-4x = 2(-3x - 6)

-4x = -6x - 12

2x = -12

x = -6 , which is one of the choices
