System of Linear Equations in 2 variables
A system of linear equations usually has a single solution, but sometimes it can have no solution (parallel lines) or infinite solutions (same line). This article.get watch and aaj jaane ki zid na karo hindi lyrics
In mathematics , a system of linear equations or linear system is a collection of two or more linear equations involving the same set of variables. For example,. A solution to a linear system is an assignment of values to the variables such that all the equations are simultaneously satisfied. A solution to the system above is given by. The word "system" indicates that the equations are to be considered collectively, rather than individually. In mathematics, the theory of linear systems is the basis and a fundamental part of linear algebra , a subject which is used in most parts of modern mathematics. Computational algorithms for finding the solutions are an important part of numerical linear algebra , and play a prominent role in engineering , physics , chemistry , computer science , and economics.
A system of equations refers to a number of equations with an equal number of variables. We will only look at the case of two linear equations in two unknowns. The situation gets much more complex as the number of unknowns increases, and larger systems are commonly attacked with the aid of a computer. This is the standard form for writing equations when they are part of a system of equations: the variables go in order on the left side and the constant term is on the right. The bracket on the left indicates that the two equations are intended to be solved simultaneously, but it is not always used. When we talk about the solution of this system of equations, we mean the values of the variables that make both equations true at the same time. There may be many pairs of x and y that make the first equation true, and many pairs of x and y that make the second equation true, but we are looking for an x and y that would work in both equations.
A Linear Equation is an equation for a line. A System of Linear Equations is when we have two or more linear equations working together. Can you discover the values of x and y yourself? Just have a go, play with them a bit. There can be many ways! In this case both equations have "y" so let's try subtracting the whole second equation from the first:.

Systems of Linear Equations
A system of linear equations means two or more linear equations. In plain speak: 'two or more lines' If these two linear equations intersect, that point of intersection is called the solution to the system of linear equations. A system of equation just means 'more than 1 equation. A system of linear equations is just more than 1 line, see the picture:. The solution is where the equations 'meet' or intersect. The red point is the solution of the system. There can be zero solutions, 1 solution or infinite solutions--each case is explained in detail below.
