Matrices Inversion Method _ Class 9th _ Ex#1.6, Q#1

🔹 System of Linear Equations: An equation of the form: ax + by = k ........ (i) Where a ≠ 0, b ≠ 0, k ≠ 0 is called a non-homogeneous linear equation in two variables x and y. Two linear equations in the same two variables such as: a1x + b1y = k1 a2x + b2y = k2 form a system of non- homogeneous linear equations in the two variables x and y if constant term k1, K2 are not both zero. If in the equation (i) , k = 0, that is, ax + by = 0, then it is called a homogeneous linear equation in x and y. 🔹 Solution of Simultaneous Linear Equations: System of two linear equations in two variables in general form is given as ax + by = m cx + dy = n Where a, b, c, d, m and n are real numbers. This system is also called simultaneous linear equations. We discuss here the following methods of solution. (i). Matrix Inversion Method (ii).
