One example would be to isolate variables. For example, when you need to find the velocity of an object, the law of conservation of energy states the Ek is equal to Ep, to mv2/2 is equal to mgh, and thus v equals root 2gh, or (2gh)1/2.

Law that states that energy cannot be created or destroyed?

The law of Conservation of Energy. Actually, that law has been superceded now by a slightly different one. Recently (maybe 100 years ago) it was learned that energy can become mass and mass can become energy. So the law had to be modified to say that the total combination of mass and energy can't be created or destroyed.
