## Explain in Detail :Linear Algebra – The Basics

Linear algebra is the study of mathematical problems that can be best explained in terms of linear equations. These equations are usually represented in mathematical notation using letters to represent unknown quantities and using a plus or minus sign to indicate whether a quantity is to be added to or subtracted from another.

A typical linear equation might look something like this:

x + 2y = 3

This equation says that the sum of x and 2y is equal to 3. In other words, if we add 2y to x we will get 3.

Linear equations can be solved by using a technique called substitution. This technique involves solving one of the equations for one of the variables and then substituting that value into the other equation. For example, suppose we wanted to solve the equation x + 2y = 3 for y. We could solve it by solving for y in the first equation and then substituting that value into the second equation.

y = 3 – x

x + 2(3 – x) = 3

x + 6 – 2x = 3

x = 3

## Linear Algebra Matrix

In linear algebra, a matrix is a two-dimensional array of numbers, symbols, or other mathematical objects. The numbers in a matrix are called its elements or its entries. Matrices are usually denoted by capital letters of the alphabet, such as A, B, and C. Matrices can be added, subtracted, multiplied, and divided, just as numbers can.

## Different Types of Matrices

There are a few different types of matrices that you might encounter in your studies.

A square matrix is a matrix with the same number of rows and columns.

A rectangular matrix is a matrix with more rows than columns.

A triangular matrix is a matrix with more columns than rows.

An identity matrix is a square matrix with all zeros except for the main diagonal, which is all ones.

## The Study of Linear Algebra

Linear algebra is the study of mathematical problems that can be best explained in terms of linear equations. A key focus of linear algebra is the development and analysis of mathematical methods for solving systems of linear equations. In addition, linear algebra also investigates the properties of vector spaces and linear transformations.
