                              K  =  J   

                              K  =  4 • (J – 144)   

 

                               K  =  4 • (J – 144)   

K = J   therefore      J   =  4 • (J – 144)   

 

                                J  =  4J – 576    

 

                            576  =  3J    

 

                                 J  =  192   

 

K = J  therefore        K  =  192
