Mathematics

Substitution method

प्रतिस्थापन विधि

In this Class 9 Mathematics topic from Linear Equations in Two Variables, students learn the substitution method for solving a pair of linear equations. They practise rearranging one equation to express one variable in terms of the other, substituting that expression into the second equation, and then finding both unknowns step by step. The topic also develops accuracy in simplifying expressions, checking solutions in the original equations, and understanding how algebra can solve problems involving two related quantities.

Practice questions
