The algebraic property of equality that is represented by the above expression is the subtraction property.
3.
Given
If a = b, then a can be substituted for b (or b for a) in any equation or expression.
The algebraic property of equality that is represented by the above expression is the substitution property.
4.
Given
If
, then
.
The algebraic property of equality that is represented by the above expression is the division property.
5.
Given
If
, then
The algebraic property of equality that is represented by the above expression is the addition property.
6.
Given
sum:
,
difference:
The algebraic property of equality that is represented by the above expression is the distributive property.
7.
Given
If a = b and b = c, then a = c. If AB = CD and CD = EF, then AB = EF. If m<A = m<B and m<B = m<C, then m<A = m<C.

multiplication property.
11.
Given
If AB = BC, then AB - 2 = BC - 2.
The algebraic property of equality that are represented by the above expression is the
subtraction property.
12.
Given
m<A = m<A
The algebraic property of equality that are represented by the above expression is the
refrexive property.
13.
Given
If AB = CD and CD = 6, then AB = 6
The algebraic property of equality that are represented by the above expression is the
transitive property.
