Question

Use complete sentences to describe why it is necessary to do the same thing to both sides of an equation to perform valid operations.

Answer 1

It is necessary to do the same thing to both sides of the equation to assure that the equality holds between the two sides.

Answer 2

The reason why it is important to keep each side of a problem the same is because if you do, your problem will be unequal. This will mess the whole problem up.
