Sum of torque equals 0 for rotational equilibrium?

0 - -8 = 8

Torque is analogous to force. As Force produces a change in the state of linear motion of a body, Torque produces a change in the state of rotational motion of a body. The unit is newton meter (Nm)...

First sum the terms with x: 9x + (-3)x = 6 x. Then sum the terms without x: -11 + (-13)x = -24. Then 6x - 24 =0 or x = 24/6 = 4

The second version (mN) would likely be confused with milli-newton.

This is because of the identity property of multiplication Anything mutiply by zero is zero. When you multiply a number by a different number, you take as many groups of the first number as there are...
