## FAQs on RD Sharma Class 12 Solutions Chapter 8 - Solution of Simultaneous Linear Equations (Ex 8.1) Exercise 8.1

**1. What are some uses of Linear Equations in real life?**

Linear Equations have many real-life examples like the distance you cover when you jog from one spot to another or measuring the railway coordinates of two locations in India. The characteristic of a Linear Equation is that it includes a rate of change. It can be used to solve equations and questions related to two or more variables in Money, Age, Geometry, Distance, Wages,Pressure and Force. It helps us express problem statements as accurate Algebraic Expressions. By the end of analysing and representing the data we can also go back and see if the result meets the criterion originally defined

**2. How can I score well in Linear Algebra in Class 12?**

As we keep saying, Mathematics in Class 12 cannot be taken lightly. At the same time don’t take it so seriously that it gives you stress! Take a balanced, well thought-out approach. Take down your doubts/challenges and strong points in two different sections. Get your doubts clarified with our Expert Teachers and strengthen your strengths further by using our revision notes. Keep practising consistently with the help of our NCERT Solutions and RD Sharma Solutions. You can also choose to study and practise in groups. It makes study fun and generates a deeper understanding

**4. What are some methods to solve Linear Equations?**

As we know solving a Linear Equation means to find the value of the unknown variables in the equation. There are 6 major methods of solving methods which are as follows:

Elimination Method - addition or subtraction is used to equate or eliminate one of the coefficients.

Substitution Method - it is to substitute one equation for another.

Graphical Method - the coordinates are plotted on a graph and the intersection point is found.

Matrix Method - can be used to solve complex equations with two or more variables.

Cross Multiplication Method - another technique to simplify the equation.

The Method of Determinants - Like matrices, this one also helps us solve complex linear equations.

**5. What are the components and applications of Linear Algebra?**

Linear Algebra is used to study physical objects such as planes, lines and rotations. It is one of the fundamentals of Vector Geometry and used widely in disciplines such as Physics and Advanced Forms of Engineering. Some components of Linear Algebra include Vectors, Matrices, Linear Functions, Linear Algebraic Equations and so on. Vectors for instance can be defined as a physical quantity possessing both magnitude and direction. It is used in linear programming, ranking practises in search engine operations, creating 2D and 3D graphics, in automated technologies such as facial recognition systems, etc.
