Identifying Equivalent Expressions

The video tutorial demonstrates how to prove that the expressions 3x + 2 and 2 + 3x are equivalent using the commutative property of addition. It explains that rearranging the terms does not change the value of the expression. The tutorial verifies this by substituting different values for x in both expressions and showing that they yield the same result. The lesson concludes by reinforcing the concept of expression equivalence.
