Using this method, you isolate the variables and substitute one of them to solve for the other. These are worksheets you can use to practice the method.Solving Systems of Equations by EliminationSolving Systems of Equations by Elimination can be a bit tedious. Here is a fun way to get students engaged and keep them on task. Students often find solve the systems of equations by elimination worksheets boring but they LOVE scavenger hunts! Topic: Solving Systems of Linear Equations in Two Variables. Objectives: This lesson will help students learn the substitution and elimination methods of solving a linear equation by first using the graphing calculator to graph and construct tables of linear equations. Materials: Graphing calculator, overhead display, handout (included) Note: When solving systems with more than two unknowns by substitution or elimination methods, make sure to incorporate all the equations. For instance, in a system of three equations in three variables, you may use equations 1 and 2 to eliminate one variable. Then, you should use equation 3 and either 1 or 2 to eliminate the same variable.
