Question 714949: I want to know what property(addition, subtraction, substitution, transitive, partition) is used, if x=2 and y=5, then xy=10
Answer by jim_thompson5910(35256) (Show Source): You can put this solution on YOUR website!
x*y = x*y ... reflexive property (any number is ALWAYS equal to itself)

x*y = 2*5 ... substitution property (ie you're replacing x with 2 and y with 5 on the right side)

x*y = 10 ... multiplication

So it sounds like the answer is substitution
