I have some trouble on setting of n-linear equations in matlab.I don't know how can I declare in matlab.I need matlab code for setting of n-linear equations..
Answer Snippets (Read the full thread at stackoverflow):
Here you can find great example: http://blogs.mathworks.com/pick/2007/09/13/matlab-basics-video-solving-linear-equations/ (video!)
See also these pages....
You can write n-linear equations as one matrix equation to solve it.

I have a system of 22 linear equations (exactly 22 equations and 22 unknowns) which are dynamically generated in an Excel spreadsheet. Is there a way to have Excel solve the system and produce a value for each of the unknown variables?
Another SO question...

You should not ever consider Cramer's rule to solve a linear system to solve a linear system.

We are using a programming language that does not have a linear regression function in it. We have already implemented a single variable linear equation:
y = Ax + B
and have simply calculated the A and B coefficents from the data using a solution similar...

Here's.
linear equations
k = aX1 + bY1 + cZ1 k = aX2 + bY2 + cZ2 k = aX3 + bY3 + cZ3
What you can doYes, it's an easy linear algebra problem if you think of it the way Gil Strang does it.

There are lots of different methods you can apply to solve linear systems combinatorical problems (picking one element out of a finite set).
You simply don't.

Does anyone know of a website / free application which can graph simple linear equations in one variable on a number line?
Would need to be able to show N, Z and R solutions.

X - 3) - 2(3x - 3) < 18
12x - 9 - 6x + 6 < 18 as -2 x -3 = 6
6x < 21
x < 3 1/2 You are wrong because it is---
6(4x - 3) / 2 - 6(3x - 3) / 3 < 3
= 3(4x - 3) - 2(3x - 3) < 3
= 12x-9-6x+6 < 3
= 6x-3 < 3
= 6x < 6
= x < 6
