Let’s take simultaneous equation with 3 variables. ……………(1) …………..(2) …………….(3) To solve simultaneous equation with 3 variables Step 1: Take 2 equations, say (1) & (2) to remove any one variable, say z. Mark...
Let’s take a pair of linear equation: ……………..(1) ……………..(2) With the help of coefficient of equations (1) & (2) we can easily determine if the solution of the simultaneous equations will be Unique Solution,...
Approach 2 : Substitution MethodIn this method, we express one of the variables in terms of the other in 1 of the equation and then substitute the value of the variable in the other...
Approach 1 : Elimination Method In this method we try to eliminate one of the two variables in the linear equations. After elimination, an equation with only one variable is left. Simplifying the equation,...
A set of 2 (or more) linear equations in 2 (or more) variables which are satisfied simultaneously by a same unique solution are called as Simultaneous Equations.e.g. 2x + 3y = 14and 2x –...
