    This video does a bunch of examples of solving very simple, one-variable, one-step equations. They start out using addition and subtraction to solve, and eventually get into multiplying or dividing to solve. This is a great introduction to solving simple equations, and ends with some more complicated equations where you must combine like terms first.
