Need done asap what property justifies the statement below if a =2z and 2z=b then a = b
1. reflexive property
2. transitive property
3. substitution property
4. symmetric property

transitive property

Step-by-step explanation:

According to transitive property, if there is some relation between a and b by some rule , and then there same relation between  b and c by some rule, then

A and C are related to each other by some rule.

Example:

A = B

B=C

then by transitive property

A=C

As value of A and C are same that is B we can say that A is equal to C whose value is B.

Given

a =2z and 2z=b

here both c and b has value equal to Z , Thus, they follow transitive property.
