2-45.

When writing an expression for part (a) of problem 2-44, Ricardo wrote 2*x* − 3 − (*x* + 1) while Francine wrote − 3 + 2*x* − (*x* + 1). Francine states that their expressions are equivalent. Is Francine’s conclusion true or false? Use algebraic properties to **justify** your conclusion. Homework Help ✎

Francine's conclusion is true because of the Commutative Property of Addition.
