Lateral load in one plane in a structure is resisted by four different systems:

cantilevered column, shear wall, brace frame, and moment resisting frame. The

stiffness $K$ of each system is given in the diagram. Using the information provided,

determine how much of the $80$ kip lateral load is resisted by each system.
