Answer:

Step-by-step explanation:

Lets consider that there are 3 cubes on the left side of the pan and 9 cubes on the right side.

There are 6 more cubes on the right side than on the left side.

To balance the pan, one side should have (3+9)/2 = 6 cubes on one side.

So 3 cubes from the right side must be moved to the left side such that both sides have 6 cubes and then the pan would be balanced.
