Statics/Three-Dimensional Equilibrium

There are six equations expressing the equilibrium of a rigid body in 3 dimensions.

Sum of Forces: $$\sum_{}^{} F_x=0$$,       $$\sum_{}^{} F_y=0$$,        $$\sum_{}^{} F_z=0$$

Sum of Moments: $$\sum_{}^{} M_x=0$$,       $$\sum_{}^{} M_y=0$$,        $$\sum_{}^{} M_z=0$$

To solve three dimensional statics problems:

Im mad bc why r there only 5 problems here i need the six specific equilibruim equations for a 3 dimensional system. HELP BRO.
 * Resolve force components
 * Resolve moments about a point
 * Resolve moments about a line or axis. See Scalar Triple Product

Knowing how to find the Determinate of a matrix can help a lot here.
