Solving Linear Systems with non-integer coefficients by using some soft ware

The present study aims to look for optimization programs to solve systems of linear equations and so these methods requiring less mathematical skills and effort mentally contributes to less than reliable in various applications for non-specialists in mathematics. And then compare this software to find the difference between them and the errors if it is existed. The case study involved a written system contained a non-integer coefficient to note the differences in accuracy of solutions. In this case identical solutions of all systems up to 10-6.
