Subtract the new equations common coefficients have same signs and add if the common coefficients have opposite signs. Solve the system of equations by elimination beginaligned 3x - y 5 x y 3 endaligned Solution. Use elimination when you are solving a system of equations and you can quickly eliminate one variable.
How to Solve a System of Linear Equations Using The Elimination Method aka The Addition Method aka The Linear Combination Method Step 1.
Before you can eliminate. Equate the coefficients of the given equations by multiplying with a constant. General form of linear equation in two variables is ax by c 0 Procedure for elimination method. Divide both sides by the coefficient of the left side.
