The following video demonstrates how we can solve for a variable in an equation or formula. This is necessary sometimes because a formula may express a relationship one way, but we may find that it is necessary to express that relationship with respect to a different quantity. For example in the formula A= bh we may be asked to express the relationship with respect to the base. In that case the formula would read b=A/h.
Unfortunately I will have to post this video again as the revised explanation of the last problem was not complete.
