Video on Substitution Method and Elimination Method in Hindi

Introduction
Substitution and elimination are two methods used in solving systems of linear equations. These methods have different approaches but aim to find the same solution.

Substitution Method
The substitution method involves solving one of the equations for one of the variables, then substituting the result into the other equation. This will result in an equation with one variable, which can then be solved to find the value of that variable. The value obtained can then be substituted into either of the original equations to find the value of the other variable.

Elimination Method
The elimination method involves adding or subtracting the equations in such a way that one of the variables is eliminated, resulting in an equation with one variable that can be solved. The solution obtained can then be substituted into either of the original equations to find the value of the other variable.

Elimination Method Part 1
In elimination method part 1, we focus on eliminating one variable by adding or subtracting the two equations. To do this, we need to ensure that the coefficients of one of the variables have the same magnitude but opposite signs in both equations. We then add or subtract the equations to eliminate that variable and solve for the other variable.

Conclusion
The substitution and elimination methods are important tools in solving systems of linear equations. By understanding the steps involved, we can easily solve any system of two linear equations with two variables.
