To Find: the value of
Answer to Problem 70E
Solutions of the system of equation is
Explanation of Solution
Given information: System of equations are
Concept Used: Gauss-Jordan Elimination is the process of performing row operations to transform any matrix into row echelon form. In reduced row echelon form, each successive row of the matrix has less dependencies than the previous
Calculation:
System of equations are:
Gauss-Jordan Elimination is used to obtain the row echelon form of the linear system above
Write the augmented matrix:
Now, apply elementary row operations until obtain zeros above each of the leading
The matrix is now in reduced row echelon form. Converting back to a system of linear equation
This solution can be written as the ordered triple
