What is the substitution postulate?
Substitution Postulate A quantity may be substituted for its equal in any expression. Division Postulate If equal quantities are divided by equal nonzero quantities, the quotients are equal.
How do you use transitive property in proofs?
Proof: If we know A = B and B = C, we can conclude by the transitive property that A = C. If we also know C = D, then we have both A = C and C = D. One more use of the transitive property will finally give us A = D. There's also the substitution property of equality.
Substitution Property of Equality
The substitution property of equality, one of the eight properties of equality, states that if x = y, then x can be substituted in for y in any equation, and y can be substituted for x in any equation.
Why is It Important?
In short, the substitution property of equality makes algebra possible. If we did not use this property in algebra, we would not be able to plug in known values for variables into mathematical expressions and equations. Even though the property is pretty easy to comprehend, it is a big deal when it comes to mathematics, especially algebra!
Examples
Let's take a look at a very simple example to start. Let's say that we have 5 x and we know that x = 5. We can use the substitution property of equality to plug in the value of x into 5 x:
