To solve a matrix on a TI-84 calculator, first, enter the matrix by pressing the MATRIX
button, then select EDIT
to define your matrix dimensions and input the values. After entering the matrix, exit the edit mode, then access the MATRIX
menu again to select your matrix for operations like finding the inverse, determinant, or performing row operations. For example, to find the inverse, select the matrix, then press x^-1
and hit ENTER
. The calculator will display the result.
Press 2ND MATRIX (above x-1). Select EDIT at the top with the arrow keys. The select matrix [B] and press ENTER. You can now edit the matrix. (Use the numbers at the upper right to set the size.)
please send me answer for me.....

It isn't clear what you want to solve for. If you want to find the matrix, there is not a unique solution - there are infinitely many matrices with the same determinant.
Gauss Elimination
True
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.
Please clarify what you want to "solve". There are several operations you can do with matrices, such as add them, multiply them, transpose them, etc.
by elimination,substitution or through the matrix method.
You can solve the system of equations with three variables using the substitute method, or using matrix operations.
There's more than one answer, but most ppl is now starting to use engines on the internet to solve problems and those engines uses matrix to retrieve data from sources.
determinents - you cross multiply and find the difference.
