## Summary of RD Sharma Class 12 Solutions Maths Chapter 8- Simultaneous Linear Equations

RD Sharma Solutions Class 12 Maths Chapter 8- Simultaneous Linear Equations an essential one from your examination point of view. You will be able to solve the questions of this chapter effortlessly once you have understood the chapter, Adjoint of a Matrix. This chapter requires an in-depth understanding of concepts and rules. It is also important to keep practising each numerical until you perfect it. Here are some important topics you need to understand while revising the chapter:

System of Linear Equations

To understand the concepts of this chapter, it is important to know what a system of linear equations means. A collection or group of linear equations consisting of the same set of variables is said to be a system of linear equations.

Consistent System

In this portion of the chapter, you will learn how to check the consistency of linear equations. A linear system of equations is said to be consistent when there is at least one set of values for the unknowns which satisfies each equation. This means that each equation holds true as an identity when substituted. This is done by first finding out the ratios of the coefficient of the equations.

Homogeneous and Nonhomogeneous Systems

It is important to understand the meaning of homogeneous and non-homogeneous systems. Homogeneous systems are the systems of linear equations whereas all the constant terms are zero. For e.g., the system of linear equation Ax=b is homogeneous if b=0. Here, if b is not equal to 0, then it is a non-homogeneous system.

Coefficient Matrix

In this chapter, you will be solving the system of linear equations with the coefficient matrix. A coefficient matrix consists of the coefficients of variables that are present in a set of linear equations.

Solutions of System of Linear Equations

In this portion of the chapter, you will learn the importance of solutions to systems of linear equations. When the values of the variables satisfy all the linear equations, they are known as solutions of a system of linear equations.
