33. System Of Linear Equations - Wikipedia, The Free Encyclopedia In mathematics, a system of linear equations (or linear system) is a collection of linear equations involving the same set of variables. For example, http://en.wikipedia.org/wiki/System_of_linear_equations

System of linear equations From Wikipedia, the free encyclopedia Jump to: navigation search A linear system in three variables determines a collection of planes . The intersection point is the solution. In mathematics , a system of linear equations (or linear system ) is a collection of linear equations involving the same set of variables . For example, is a system of three equations in the three variables x y z . A solution to a linear system is an assignment of numbers to the variables such that all the equations are simultaneously satisfied. A solution to the system above is given by since it makes all three equations valid. In mathematics, the theory of linear systems is a branch of linear algebra , a subject which is fundamental to modern mathematics. Computational algorithms for finding the solutions are an important part of numerical linear algebra , and such methods play a prominent role in engineering physics chemistry computer science , and economics . A system of non-linear equations can often be approximated by a linear system (see linearization ), a helpful technique when making a

34. Simultaneous Equations - Wikipedia, The Free Encyclopedia In mathematics, simultaneous equations are a set of equations containing multiple variables. This set is often referred to as a system of equations. http://en.wikipedia.org/wiki/Simultaneous_equations

Simultaneous equations From Wikipedia, the free encyclopedia Jump to: navigation search This article needs attention from an expert on the subject . See the talk page for details. WikiProject Mathematics or the Mathematics Portal may be able to help recruit an expert. (November 2008) In mathematics simultaneous equations are a set of equations containing multiple variables. This set is often referred to as a system of equations . A solution to a system of equations is a particular specification of the values of all variables that simultaneously satisfies all of the equations. To find a solution, the solver needs to use the provided equations to find the exact value of each variable. Generally, the solver uses either a graphical method , the matrix method, the substitution method, or the elimination method. Some textbooks refer to the elimination method as the addition method, since it involves adding equations (or constant multiples of the said equations) to one another, as detailed later in this article. This is a set of linear equations , also known as a linear system of equations Solving this involves subtracting x y = 6 from 2 x y = 8 (using the elimination method) to remove the y -variable, then simplifying the resulting equation to find the value of
