2. The value of the green rectangle will balance the scale. What could replace the green rectangle to balance the scale? =

3. Recall that you can do several things to both sides of a scale and keep it balanced. Try to isolate the green rectangle by itself on one side to find the value of the green rectangle. Give the value for x and explain how you determined the answer. =

4. We found the value of the green rectangle by removing 3 yellow squares from each side. Can you think of another way you could get the green rectangle by itself? Give the value for x and explain how you determined the answer. =

5. Try to isolate the green rectangle by itself on one side to find the value of the green rectangle. Keep the scale balanced. Give the value for x and explain how you determined the answer. =

6. =

7. Check our work. =
