Expert Solution & Answer
Chapter 7.3, Problem 41E
Solution
To identify: The system of equations by finding the reduced row echelon form for the augmented matrix.
The value of
Given information:
The given equation is.
Explanation:
Consider the given information.
To obtain the augmented matrix of a system, write out the coefficients as entries, aligning those with the same variables, and placing 0 for variables that are not present. The last column corresponds to the constants.
So, its corresponding augmented matrix is:
Apply elementary row operation to obtain a reduced row echelon from of the matrix.
This corresponds to the system of equation.
Since
So, the value of
