Lets review the steps for each method. The third method of solving systems of linear equations is called the Elimination Method. In the elimination method you either add or subtract the equations to get an equation in one variable.

Go through the solved example given below to understand the method of solving simultaneous equations by the elimination method along with steps. In fact Gauss-Jordan elimination algorithm is divided into forward elimination and back substitution. If the coefficients of one of the variables are the same and the sign of the coefficients are opposite we can add the equation to eliminate the variable.

The Elimination is one of the three methods to solve systems of linear equations in two variables the other two being graphing and substitution method. To solve a system of equations by elimination we transform the system such that one variable cancels out. Solving Simultaneous Linear Equations Using Elimination Method.

7x 5y 19 -7x-2y -16 graphing substitution elimination or distributive. Solve the two equations in steps three and four for the two variables they contain. 1 4 x 2y 12 4x 8y 24 6 6 2 4x 8y 20 4x 2y 30 7 1 3 x y 11 2x y 19 10 1 4 6x 5y 1 6x 4y 10 1.
