X₁ + X2 - 3x3
2x₁ + 7x2 + 2x3
X1 + 5x₂ 6x3
X4 = 7
4x4 = -2
3x4 = 8
= 4
O The system has a unique solution because the determinant of the coefficient matrix is nonzero.
O The system has a unique solution because the determinant of the coefficient matrix is zero.
O The system does not have a unique solution because the determinant of the coefficient matrix is nonzero.
O The system does not have a unique solution because the determinant of the coefficient matrix is zero.
Re-order the equations, so that the coefficient matrix is diagonally dominant.
