identical identities
" like terms"
They are "like terms".
Identical terms are expressions that contain the same variables raised to the same powers and coefficients. For example, in the expression (3xy) and (3xy), both terms are identical because they have the same coefficient (3) and the same variables (x and y) in the same form. Similarly, (5a^2b) and (5a^2b) are identical terms.
Unlike terms.
We often call "undefined terms" variables. Their value is not known; it can vary. And thus the name we assign them is variable.

The two variables must be identical.
You can't. You can only subtract like terms. Like terms must have exactly the same variables and exponents on the variables.
like terms - are terms that have identical variable parts and constant terms
