Describe how to verify whether expressions are equivalent and explain the purpose of verifying equivalent expression

Equivalent expressions are expressions with equal values.

The purpose of verifying equivalent expressions is to check if the given expressions hold the same values or not.

The expressions are not given. So, I will give a general explanation.

Assume the expression is:

The above expression is an equivalent expression because x + x and 2x hold the same value.

Another expression is:

The above expression is not an equivalent expression because x + x and 3x do not hold the same value.
