Write About the Math
How far has the hiker walked? How did you use inverse operations?¿Qué distancia ha caminado la excursionista? ¿Cómo usaste las operaciones inversas?
Say your answer to a partner first. Then write it, using at least two of these words:
Model: I can undo the addition to get the variable by itself. — Students recognize 23 is added to n and that subtracting 23 (the inverse operation) from both sides will isolate n.
