Moving Variables

The way we move one variable to the other side of the equal sign is that you do the inverse operation that you have in your problem.For example 16j=12-4j for 4j you will add 4j to 16j.The relationship between addition and subtract is if we have addition in our problem we do subtraction because that is the inverse operation and the same goes for subtraction. The phrase what we do to one side we must do to the other side and we can relate it to a balance scale because in a balance scale both sides must be equal or it wont be balanced just like the problem the we need to move the variable to one side.We need to do the inverse operation to have only the variable on that side.Then you do the inverse operation again and than you already solved for your variable.
