Newton's Revised Third Law of eMotion

"for every great happiness, there is an equally great misery."
"for every great love that is felt, there is an equally strong relationship that is hurt"
"for every cherished moment, there is also a moment you wished never happened"
"for every loving embrace, there is an equally cold parting"
therefore in mathematical formula :

∑of [(7X)(9y)(14z)(13a)]∩happiness=∑of [(24x)(14y)(1a)] ∩ sadness
