The solution of the system of equations
Answer to Problem 41AYU
Solution:
The solution of the system of equations
Explanation of Solution
Given information:
The system of equations
Explanation:
Using system of linear equations
Then the original system of equation can be written compactly as
Hence,
Here,
To find inverse of matrix
Step 1: Form the matrix
Step 2: Transform the matrix
Step 3: The reduced row echelon form of
Consider the matrix
Use
Use row operation
Use
Use
Thus, the inverse of the matrix
Now,
Therefore,
Thus, the solution of the system of equations
