How do you solve simultaneous equations using matrices?
There are many ways of doing this. For example Gaussian elimination, diagonalising, but the simplest to explain is matrix inversion (I'm assuming some knowledge of matrices here, and unfortunately some of the matrix formatting is a little off due to limitations in the editor): Any system of simultaneous equations can be rewritten as the matrix equation A.v = u The coefficients of the variables become the entries in the square matrix, A. To solve the matrix equation we need to invert A, and then multiply by the inverse, giving us I.v = A-1.u where I is the identity matrix. As an example take the following system of equations: 2x - 3y = 1 4x - 5y = 5 The matrix version of this equation is { 2 -3 } { x } = { 1 } { 4 -5 } { y } { 5 } A v u It's clear that if you multiply out the matrix row by row, you get the original set of equations. In our case I = { 1 0 } { 0 1 } A-1 = { -2.5 1.5 } { -2 1 } (Finding the inverse of a matrix is a whole other question) so A-1.u = { 5 } { 3 } Therefore we have x = 5, and y = 3. Inversion of A is the most difficult step, though this can easily be done with a computer.

True
How do you solve 4 equation with 4 unknows?
Create a matrix of the coefficients of each equation. The solutions to the equations should make up the rightmost column of the matrix. Then, row reduce the matrix until you are able to rewrite the equations and solve them. The matrix should be a 4x5 matrix (4 rows and 5 columns) for four equations with four variables. This is known as a system of equations.
How do you solve 3 dimensional equations?
You can solve the system of equations with three variables using the substitute method, or using matrix operations.
Solve linear equations with complex coefficients on both sides?
You would solve them in exactly the same way as you would solve linear equations with real coefficients. Whether you use substitution or elimination for pairs of equations, or matrix algebra for systems of equations depends on your requirements. But the methods remain the same.
How can you solve problems involving equivalent expressions?
In the same way that you would solve equations because equivalent expressions are in effect equations

Why are equator important?
Equations allow you to solve mathematical problems.
Why inversion of matrix is usefull?
The most common use for inverted matrices is to solve a set of simultaneous equations.
How can we utilize equations to solve problems?
You can use them for POE, process of elimination.

How do you solve a system of equation with 3 equations and 3 variables?
If you know matrix algebra, the process is simply to find the inverse for the matrix of coefficients and apply that to the vector of answers. If you don't: You solve these in the same way as you would solve a pair of simultaneous linear equations in two unknowns - either by substitution or elimination. For example, change the subject of one of the equations to express one of the variables in terms of the other two. Substitute this value into the other two equations. When simplified, you will have two linear equations in two variables.
How are word problems with equations different from word problems with expressions?
It may be possible to solve equations. Expressions cannot be solved until they are converted, with additional information, into equations or inequalities which may have solutions.
