The Reflexive Property

The Substitution Property

The Addition Property

The Subtraction Property

a = a.

If a = b, then a can be substituted for b in any expression.

If a = b, then a + c = b + c

If a = b, then a - c = b - c

The Reflexive Property

a = a.

The Substitution Property

If a = b, then a can be substituted for b in any expression.
