Answer to Problem 11RE
The system of linear equations are
And the solutions of the system are
Explanation of Solution
Given information:
The given augmentedmatrix is
Calculation:
A matrix derived from a system of linear equations is the augmented matrix of the system. Moreover, the matrix derived from the coefficients of the system is the coefficient matrix of the system.
Let the system of linear equations are
The augmented matrix is
The system of linear equations are
Substitute the value of
Substitute the value of
Hence the system of linear equations are
And the solutions of the system are
