What is the golden rule for solving equations?
Do to one side of the equation what you do to the other! An equation is like a scale. When we put something on one side or take it away, the scale (or equation) is thrown off balance. When solving mathematical equations, we must always balance the scale (or equation) so that both sides are ALWAYS equal.
