Pair Of Linear Equations In Two Variables - Algebraic Method - Substitution Method Video By Lets Tute

Linear equation in two variables' means an equation which has two variables (like x & y) with power 1. While these can be solved 'graphically', however, there are cases when coordinates of points representing the solution are non-integral. In order to avoid mistakes while reading such coordinates, an alternative 'algebraic' method is used. This session specifically addresses the 'substitution method' wherein equation is solved by substituting one variable with another.
