Final answer:
An identity equation has infinite solutions because it is always true for all values of the variable(s).
Step-by-step explanation:
If an equation is an identity, it means that it holds true for all possible values of the variable(s) in the equation. In other words, an identity is an equation that is always true, regardless of the values of the variables. Therefore, an identity has infinite number of solutions, since any value substituted into the equation will satisfy it.
