Question 477269: Is There only one method to find the solution to a system of equations?
Answer by robertb(5830)   (Show Source):
You can put this solution on YOUR website! No. For a finite system of linear equations having finite number of variables one can use the regular substitution/elimination method, Gaussian elimination, or Gauss-Jordan reduction. If the number of equations is equal to the number of variables one can use Cramer's method/rule. There might still be other clever methods out there to solve systems, as claimed by others.
