Solving Systems of Linear Equations Using Matrices
Matrices have many applications in science engineering and math courses This handout will focus on how to solve a system of linear equations using matrices |
|
Systems of Linear Equations; Matrices
This is common practice on many graphing calculators but not in mathematical Matrices serve as a shorthand for solving systems of linear equations |
Matrices can be used to compactly write and work with systems of equations.
As we have learned in previous sections, matrices can be manipulated in any way that a normal equation can be.
This is very helpful when we start to work with systems of equations.
What is the system of linear equations in matrix algebra?
A system of linear equations can be represented in matrix form using a coefficient matrix, a variable matrix, and a constant matrix.
Consider the system, 2x+3y=85x−y=−2 .
The coefficient matrix can be formed by aligning the coefficients of the variables of each equation in a row.
How do you solve a matrix problem?
We can solve matrices by performing matrix operations on them like addition, subtraction, multiplication, and so on.
We have to take care of the orders while solving matrices.
For the addition/subtraction of 2 matrices, their orders should be the same.
Can you solve systems of equations with matrices?
Matrices can be used to solve systems of equations.
But first, we must learn how to represent systems with matrices.
