    You have proven that it is an identity (t=t). There are an infinite number of solutions.

    Hi, your instructor wanted you to use the Distributive Law: a(b + c) = ab + ac And you it looks like you did a fine job without even knowing it xD Your solution is not wrong. T = T has infinite solutions.
