Question 311581:  is xz+xy = xz+yz   
and  
    xz+xy = xy + xz 
both using the commutative property of multiplicaction? 
 Answer by stanbon(75887)      (Show Source): 
You can  put this solution on YOUR website! is xz+xy = xz+yz 
--- 
The terms have been cummuted under the commutative addition property. 
------------------------------------------  
and  
xz+xy = xy + xz 
The terms are commuted under addition and the factors of one of the 
terms are commuted under multiplication.
