Question 370589
If you solve both systems, you'll find that the two systems have the same solution. 



If you look even more carefully, you'll notice that each equation of the 2nd system is a scaled version of its corresponding equation of the 1st equation. So in this case, the second system is really the first (ie they're the same), but the second is just written a different way.



Note: it's perfectly possible to have two different systems have the same solution.
