How to solve Linear Equations
In this section I will explain to you how to solve algebraic equations. We will first learn how to solve linear equations where the highest power of x is 1 (if you graph the equation you get a line hence linear equation). Please study all videos during your maths revision for each video will contain something new. First I will show you that solving equations is something you have been doing since kindergarten and therefore is not something te feel anxious about. Unfortunately many students think algebra is very difficult which many times is something they have understood from their parents. But that is only because those parents did not pay attention in school. Trust me, you can do it!! Then we will continue and I will teach you how to solve two-step equations and multi-step equations.
