Two systems of equations are equivalent if they have the same solution(s). This article reviews how to tell if two systems are equivalent. Examples are provided.

Determine whether a couple of given systems of equations are equivalent or not to a third given system. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video or receive hints.

In this task, students explore the linear relationship between distance traveled and taxi fare cost. Aligns with A-REI.D.10 and F-LE.B.5.

Solve systems of equation with one-step elimination (e.g., x-values or y-values cancel each other out). Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video, or receive hints.

This resource demonstrates how to solve linear inequalities step-by-step and shows four different solution formats/notations viz. inequality notation, set notation, interval notation, and the last "notation" which is more of an...
