Elimination method
विलोपन विधि
In Class 9 Mathematics, the Elimination Method is used to solve a pair of linear equations in two variables. Students learn how to multiply one or both equations by suitable numbers so that the coefficients of one variable become equal or opposites, then add or subtract the equations to eliminate that variable. They find the remaining variable, substitute it back, and verify the solution in both equations, building a clear method for solving algebraic and everyday word problems.
