Make sure to valid the answer by doing back substitution to the given equations. For example substitute the value of x = 2.32 ; y = 6.46; z = 2.43; w = 2.00 back to the original equation. If both sides of the equations are equal then you know for sure that the answer is correct. The reason is the algorithm uses Cramer's Rule and sometimes the answer is not correct.
