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

=

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.

=

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.
