**Using Matrices to Solve Simultaneous Equations**

Print; If you already know how to solve simultaneous equations then you may well wonder why people use matrices to solve them. The fact is, while simple equations with two unknowns x and y are quite easy to solve, as the number of unknowns increases so does the number of equations we have to solve.... Introduction for simultaneous equations using matrices: 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.(Source from Wikipedia) In this article

**Solving Simultaneous equations using Matrices Physics Forums**

There are two main methods used to solve simultaneous equations one is by elimination and the other is through matrices. Elimination Method Elimination is done by making the coefficients of a variable the same across two equations and then minusing the two equations to eliminate the variable for example:...

Solving Simultaneous Equations using Matrices If you want to avoid a long solution to find the unknown values in simultaneous equations then you can simply use Matrices as … how to use mlp in data mining to solve problems First we look at how to use matrices as tools to solve linear algebra problems, and as objects that transform vectors. Then we look at how to solve systems of linear equations using matrices, which will then take us on to look at inverse matrices and determinants, and to think about what the determinant really is, intuitively speaking. Finally, we'll look at cases of special matrices that mean
