Watch these videos and take notes. The first video provides examples of another type of basic equation that can be solved in one step. The second is an example of a one-step equation written in a form x/a = b. Sal Khan uses this example to highlight that division is really the same operation as multiplication. The third contains examples of the equations of the form ax = b, but in some of them a and b are fractions. Instead of dividing by a fraction (a), you can multiply both sides of the equation by its reciprocal.
