Question 392754: could someone please help?
I need to solve each system of equations using guassian elimination w/back substitution or guass-jordan elimination. here is the system of equations:
1st system:
3y-z=-1
x+5y-z=-4
-3x+6y+2z=11

2nd system:
3a+b-c=0
2a+3b-5c=1
a-2b+3c=-4
3rd system:
2w-3x+4y+z=7
w-x+3y-5z=10
3w+x-2y-2z=6
Thank you to the person who responds! I would be extremely grateful for your assistance!!!
