Question 995870: 5x + 7y + 8z = 20
8x + 3y + 10z = 70
9x + 4y + 9z = 80
I need system solution for the above system of equations by using Gaussian Elimination Method. Thanking you in anticipation.
Answer by Edwin McCravy(20056) About Me  (Show Source):
You can put this solution on YOUR website!
The solution to that system of equations is as 
follows using technology:

x = 1250/101

y = -410/101

z = -170/101

Since I do not believe that any teacher would give
a problem with such a terrible solution to do by
hand, I believe that you have made an error in
copying the system of equations.  Please check.
