associative property
Commutative property of addition of numbers.
5+x=x+5 is an example of the commutative property of addition.
zero proprtey
It defines 0 as the identity in the group of numbers with respect to addition.
symmetric property of equality
I guess you mean to ask:'x = x exemplifies what property of the relation of equality?'.If so, then the answer is:The reflexive property, which is a property of all equivalence relations.Two other properties, besides reflexivity, of equivalence relations are:symmetry and transitivity.
if (x!=x(x==y && !(y==x))(x==y && y==z && !(x==z)))puts ("Something is very wrong here");
symmetric property of equality
Isolate the variable. Get it by itself. 9+11x=89+x 9+11x-1x=89+x-1x Subtraction property of equality 9+10x=89 9+10x-9=89-9 subtraction property of equality 10x=80 x=8 division property of equality.
If: 14x = 56Then x = 56/14Therefore: x = 4
4
if x+5=9 than x=4 solved by subtraction property of equality check by substation property 4+5=9
X= x
4
Division Property of Equality
Transitive property: If 8 equals x and x equals y, then 8 equals y.
