Moving Variables

To move one variable term to the other side of the equal sign, we have to subtract a number or add a number to both sides of the equal sign.In the problem 16j= 12 - 4j, we will have to add 4j on both sides because we need to get 12 by it self. The relationship between addition and subtraction is that they are inverse operation. "What we do to one side we must do to the other side" relate to a balance scale because a balance scale has equal balance, and in solving equations you have to get the variable by it self ,It equals out.
