When solving linear systems, you have two methods — substitution or elimination — at your disposal, and which one you choose depends on the problem. The crucial point here is that elimination is a more general form of substitution, where you don't need to know what the variable is explicitly before substituting it into your equations. … This Systems of Equations (Substitutes and Elimination) Worksheet is suitable for 9th - 12th Grade.
