Question

what do algebra tiles represent in the context of two - step equations?
positive and negative variables and constants
only constants
only positive variables
only negative variables

Explanation:

Algebra tiles are a manipulative tool used to model algebraic expressions and equations, including two-step equations. They are designed to represent both positive and negative values for variables (typically rectangular tiles) and constants (typically square tiles), which is necessary to visualize and solve equations that involve both positive and negative terms.

Answer:

Positive and negative variables and constants
