The system of equations calculator is available to solve linear equations of 2 and 3 linear equations.It can be difficult for us to solve the linear equations when dealing with more than 2 linear equations.
It can be quite amazing to solve the system of equations with the algebraic method. We know there are 4 techniques to solve the system of linear equations. Here we are only solving the matrix method by the system of equations calculator.
A System of linear is a set of linear equations 2 or more than 2 normally these equations are along with two variables. Solving systems of equations of linear
Examples:
5x+6y=3
6x+9y=12
We can solve the system of equations by the system of equations calculator.
We can solve the algebraic equation by the following major methods:
The algebraic method of the solving the linear equation is subdivided into the four major methods:
“In the substitution method,we calculate the value of one variable from one equation and substitute it into another equation.”
The system of equations calculator swiftly finds the answer of the linear equations.The substitution method calculator turns the task simple and elaborate for us and we can find the values of “x” and “y” quickly.
In the elimination method we are making the coefficients of the equation equal and then subtracting them to find the answer of the variables like “x” and “y”. Solving a system of linear equations can be easily calculated if we are able to make the coefficient equal.
The cross-multiplication method is commonly used in solving systems of equations linear in nature. The cross-multiplication method is the most simplest method to solve linear equations. This method can be used to solve a system of linear equations of 2 or 3.
There are three basic method to solve the system of linear equation when you are solving the linear equation by the matrix method:
Cramer’s rule is an important method of solving systems of equations linear in. In the Cramer’s rules we are using the determinant of the matrices.This is the main reason the Cramer’s rule is also known as the determinant of the matrices.
Solving systems of equations by Cramer’s rule.
ax+by= k
cx+dy= l
$$ \left[ \begin{array}{cc|c}a & b & k\\c & d & l\\\end{array}\right] $$
The determinant in this case is”
$$ D = \begin{vmatrix}a & b \\ c & d\\\end{vmatrix} $$
$$D_x = \begin{vmatrix} a & b \\c & d\\\end{vmatrix} $$
$$D_y = \begin{vmatrix} a & b \\c & d\\\end{vmatrix} $$
The final values of variables “x” and “y” calculated by the system of equations calculator.
$$ x = \dfrac{D_x}{D} $$
$$ y = \dfrac{D_y}{D} $$
The Cramer’s rule is widely used to solve system of equations, as it is easy to find the final result of the variables by the Cramer’s rules. The system of equations calculator is elaborating the wholesome solution of linear equations.
In the inverse matrix methodology we are multiplying with the inverse of the matrix on both sides of the equation. This is a simple system of equations with the inverse matrix. It may be possible you may find difficulty in solving systems of equations. You may be amazed to experience the working style of the system of linear equations calculator.
Consider a system of Linear equation, represented as follows:
ax+by=L
cx+dy=K
$$ \begin{bmatrix}a & b\\c & d\\\end{bmatrix} \begin{bmatrix}x\\y\\\end{bmatrix} = \begin{bmatrix} L \\ K\\\end{bmatrix} $$
$$ \begin{bmatrix} a & b\\c & d\\\end{bmatrix}^1 \begin{bmatrix}a & b\\c & d\\\end{bmatrix} \begin{bmatrix}x\\y\\\end{bmatrix} = \begin{bmatrix}a & b\\c & d\\\end{bmatrix}^1 \begin{bmatrix}L\\K \\\end{bmatrix} $$
We only have to insert the values of the coefficients and the variables to find them when using the system of equations calculator.
Consider this as a method to use to solve system of linear equations.We can find the reduced echelon form by the Gaussian-Jordan elimination.
The basic steps involved in the Gaussian-Jordan elimination is as follows:
We are able to find the reduced echelon form by the Gaussian elimination calculator.
We can represents the Gaussian-Jordan elimination as follows:
Consider the linear equation:
ax+by=L
cx+dy=K
$$ \left[ \begin{array}{cc|c}a & b & L\\c & d & K\\\end{array}\right] $$
Step1:
x+3y=5
7x+9y=11
we need to place the values of the coefficients of the variables “x” and “y”. The constant values are placed in the right side matrix.
$$ \left[ \begin{array}{cc|c}1 & 3 & 5\\7 & 9 & 11\\\end{array}\right] $$
Step2:
The determinant in this case is”
$$ D = \begin{vmatrix}1 & 3 \\7 & 9\\\end{vmatrix} = -12 $$
Step3:
We need to separate the Dx and Dy values:
D_x = \begin{vmatrix}5 & 3 \\11 & 9\\\end{vmatrix} = 12
D_y = \begin{vmatrix}1 & 5 \\7 & 11\\\end{vmatrix} = -24
Step 4:
The final values of variables “x” and “y” calculated by the system of equations solver.
$$ x = \dfrac{D_x}{D} = \dfrac{12}{-12} = -1 $$
$$ y = \dfrac{D_y}{D} = \dfrac{-24}{-12} = 2 $$
x=-1, y=2
