Activity Overview

In this lesson students investigate the relationship between the solution to an equation and the solution to a new equation formed by adding, subtracting, multiplying, or dividing one or both sides of the original equation by a numerical value. Students develop an understanding of “solution-preserving moves” by thinking carefully about the structure of relationships expressed by an equation and how to exploit that structure to find a solution.
