Hi all, I'm trying to solve the following problem to find y:
The answer is meant to be y=(1,2,0), which I'm not getting. I know you can find the solution via Gaussian elimination but the lecturer was talking as if it should be a quick and easy thing to solve. I thought I could get the answers by solving it line by line (i.e. 5y=5, and then 6y=9 etc.), but that doesn't get the right answer...
I feel like I'm missing something very obvious, so any help would be greatly appreciated, thanks!
