Nettet26. mar. 2016 · When solving linear systems, you have two methods — substitution or elimination — at your disposal, and which one you choose depends on the problem. If the coefficient of any variable is 1, which means you can easily solve for it in terms of the other variable, then substitution is a very good bet. Nettet23. okt. 2012 · There are four ways to find the solution to a system of linear equations: – Graphing – Substitution – Linear Combination – Matrices Each approach has its own advantages and disadvantages, depending on the circumstances.
