Substitution Method - For Linear Equations in 2 variables (With Sums)

Download Notes

In this video, the complete explanation about substitution method for linear equations in two variables is provided in Hindi language. Few sums related to substitution method are also solved for better understanding. Substitution method or method of substitution is a part of CBSE 10th class and this method (substitution method) is used to solve the system of Linear equations in two variables. About Substitution Method : This method is used to solve linear equations in two variables, i.e. to find values of two variables 'x' and 'y' in given equations. Substitution method works like -- Use equation 1 (*we will use eqn. 1 as short form) and makes the value of x or y, its upto you! Mark this equation as eqn. 3 and put out the value of x or y (you just make from eqn. 1) into eqn. 2 given in the question. Now, the whole eqn. 2 will be converted into one variable, and it is easy for you to solve the equation. Thus, by substituting one variable, we convert the equation into one variable, which is then easy for us to solve by simple mathematics! For better understanding, check out the video.
