A matrix is a field of numbers with rows and columns. Matrices can represent many different things and have numerous applications. For example, they can be used for solving systems of linear equations or working with linear transformations; in multiple regression analyses, for working with vectors.
It really is utilized to solve specific variablesIt really is utilized to rearrange the word.
Linear Equations are equations with variable with power 1 for eg: 5x + 7 = 0 Simultaneous Equations are two equations with more than one variable so that solving them simultaneously
In general, a system of non-linear equations cannot be solved by substitutions.

Matrices are tools to solve linear equations. Engineers use matrices in solving electrical problems in circuits using Thevenin's and Norton's theories.
Yes, interchanging rows is permitted when solving a system of linear equations using matrices. This operation, known as row swapping, is one of the elementary row operations that can be performed during row reduction or when using methods like Gaussian elimination. It helps in simplifying the matrix and does not affect the solution of the system. Thus, it is a valid step in manipulating matrices.

Because linear equations are based on algebra equal to each other whereas literal equations are based on solving for one variable.
There are several methods to solve linear equations, including the substitution method, elimination method, and graphical method. Additionally, matrix methods such as Gaussian elimination and using inverse matrices can also be employed for solving systems of linear equations. Each method has its own advantages depending on the complexity of the equations and the number of variables involved.
Solving linear equations is hard sometimes.

Solving linear systems means to solve linear equations and inequalities. Then to graph it and describing it by statical statements.
No. For example, linear algebra, for example, is about linear equations where the domain and range are matrices, not simple numbers. These matrices may themselves contain numbers that are real or complex so that not only is the range not the real numbers, but it is not based on real numbers either.
Linear Algebra is a branch of mathematics that enables you to solve many linear equations at the same time. For example, if you had 15 lines (linear equations) and wanted to know if there was a point where they all intersected, you would use Linear Algebra to solve that question. Linear Algebra uses matrices to solve these large systems of equations.
If you have a system, which can be expressed as a set of linear equations, then you can utilize matrices to help solve it. One example is an electrical circuit which uses linear devices (example are constant voltage sources and resistive loads). To find the current through each device, a set of linear equations is derived.
The concept of systems of linear equations dates back to ancient civilizations such as Babylonians and Egyptians. However, the systematic study and formalization of solving systems of linear equations is attributed to the ancient Greek mathematician Euclid, who introduced the method of substitution and elimination in his work "Elements." Later mathematicians such as Gauss and Cramer made significant contributions to the theory and methods of solving systems of linear equations.
