To solve: the system of linear equations
Answer to Problem 17RE
Explanation of Solution
Calculation:
First write the augmented matrix of the given system of equations.
Consider the system of equations,
Now, use the coefficients and constant terms as the matrix entries.
So, the augmented matrix for the above system is:
Now perform the row operation
Now perform the row operation
Now perform the row operation
The matrix is now in row-echelon form, and the corresponding system is:
Now use back substitution to find x and y ,
Substitute
