It is a singular matrix.
It is a singular matrix.
One way to solve this system of equations is by using matrices. Form an augmented matrix in which the first 2x2 matrix is the coefficient matrix and the 2x1 matrix on its right is the answer. Now apply Gaussian Elimination and back-substitution. Using this method gives x=5 and y=1.
It is an arbitrary convention.
I used the matrix method to find the answer: x=4, y=-7, z=-5.
standard form
