Can you solve that two variable system?
Hi! This is my first post and hopefully someone will be able to help me! I have tried this problem atleast 10 times but I am just getting frustrated... it's not working! Here it is:
you have to solve for x, y, and z.. and I could get one but then it doesnt work for the other problems...
2x+y+z=4
3x-y+4z=11
x-y+5z=20
THANKS!I got :
x=2
z+1
y=-7
Am I correct?? HOW did you do that?! I have tried and tried with no luck.. at one point I thought x=4 so maybe I just needed to divide or something.. Maybe I'm not a lost cause after all! THANKS so much!
Thank you so much! VERY much appreciated!! If I may ask how long did it really take you to do that? I sat literally for 45 minutes trying to do it and no luck! But I did find that on my paper what Plato wrote so I need to pay more attention to the (-) and such. Thanks again!
