Watch these videos and take notes. The first video will help you to move on to even more complex equations. In the example, you have to remove the parenthesis from the both sides of the equation before attempting to solve it. The second video is an interesting example of an equation with variables on both sides involving fractions. Sal Khan chooses to multiply both sides of the equation by the common denominator and uses distributive property in order to get rid of the fractions.
