What Is Gaussian Elimination Algorithm?

In the light of mathematical analysis:

“The particular method that is used to find solution to the linear equations by arranging the augmented matrix of their coefficient numbers is known as the Gaussian Algorithm”

How to Apply Gaussian Elimination Algorithm?

Here we are going to apply this theorem on an example below. So for better understanding, just stay focused!

Example # 01:

Find solution of the following system of equations as under:

$$ 3x_{1} + 6x_{2} = 23 $$ $$ 6x_{1} + 2x_{2} = 34 $$

Solution:

No doubt our widely used gauss elimination calculator with steps will show detailed calculations to simplify these equations, but we need to analyse the scenario manually. The equivalent augmented matrix form of the above equations are as follows: $$ \begin{bmatrix} 3&6&23 \\ 6&2&34 \\\end{bmatrix} $$

Gaussian Elimination Steps:

Step # 01:

Divide the zeroth row by 3. $$ \left[\begin{array}{cc|c}1&2& \frac{23}{3} \\6&2&34 \\\end{array}\right] $$

Step # 02:

Multiply the first row by 6 and then subtract it from the zeroth row. $$ \left[\begin{array}{cc|c}1&2&\frac{23}{3} \\0&-10&-12 \\\end{array}\right] $$

Step # 03:

Go for dividing the first row by -10. $$ \left[\begin{array}{cc|c}1&2&\frac{23}{3} \\0&1&\frac{6}{5}\\\end{array}\right] $$

Step # 04:

Get going for finding the product of zeroth row and 2.

After doing that, subtract the result from the first row. $$ \left[\begin{array}{cc|c}1&0&\frac{26333333334}{5000000000}\\0&1& \frac{6}{5}\\\end{array}\right] $$

As you see on the left side of the matrix, we get the identity matrix. So the answer on the right side pof the equation would be the values of the variables in the equations. So the final results are as follows: $$ b_{1} = 5.266 $$ $$ b_{2} = 1.2 $$ The same results can also be verified by using outer free gauss elimination calculator.
