Summary[edit]
| Description |
English: A video in Swedish showing how to use "extended substitution" for solving systems of equations that are not easy to solve with conventional substitution because a lot of hard fractions are obtained. (More videos on solving systems of linear equations can be found here: http://kursplanering.se/browse?f%5B0%5D=cp_keywords%3A20&f%5B1%5D=cp_resource_type%3Avideo.)
Svenska: Den här videon visar hur man kan använda "utökad substitution" för att lösa ekvationssystem som är jobbiga att lösa med vanlig substitution, eftersom man får massa jobbiga bråktal. (Fler videor om att lösa linjära ekvationssystem går att hitta här: http://kursplanering.se/browse?f%5B0%5D=cp_keywords%3A20&f%5B1%5D=cp_resource_type%3Avideo.) |
