Algebra I: Getting started - Systems of linear equations  
   
This mini-lesson introduces systems of linear equations and explains related concepts. A system of equations is a set of equations in one or more variables, and its solution is a set of values for its variables such that when these values are substituted into the equations, the equations are 'satisfied' i.e. the results are equalities.

(Continued from above the video). If this seems too complicated, it really isn't -- when you hear the instructor explain it to you in the video above, you'll see how easy it is. Sometimes, text based explanations of mathematical concepts seem complicated, but when you actually hear from someone what they mean, they are not that difficult to understand! We'll also look at inequalities here -- an inequality, unlike an equation, does not use the = symbol, but instead uses one of these symbols: <, >, <=, >=. For example, 2x + 3y <= 5. In this inequality, whatever you plug in for values of x and y, the expression is only valid if the value of 2x + 3y is less than 5 or equal to 5.

As many of you know, Winpossible's online courses use a unique teaching method where an instructor explains the concepts in any given area to you in his/her own voice and handwriting, just like you see your teacher explain things to you on a blackboard in your classroom. This particular mini-lesson includes the teacher's instruction, practice questions as well as end-of-lesson quizzes for practice. As we mentioned above, you can enroll in our online course in Algebra I by clicking here.

The format of Winpossible's online courses is also very suitable for teachers who are using an interactive whiteboard such as Smartboard on Promethean in their classrooms, because the course lessons can be easily displayed on such interactive whiteboards. Volume pricing is available for schools interested in our online courses. For more information, please contact us at educators@winpossible.com.
