i need help with a linear equation problem. I started the problem and after a few steps i checked the problem in the solution manual and there seem to be a typo in the text so i wanted to have someone check my work if i was doing it correctly. if i made a mistake can someone please correct me and tell me what i did wrong.
1. The problem statement, all variables and given/known data
matrix[(1,1,1), (1,1,0), (1,0,0)]
2. Relevant equations
The solution in the manual had the same steps as below only the matrix was different it
was matrix [(1,1,0), (0,0,-1), (0,-1,-1)].
3. The attempt at a solution
so i first i did R2 \rightarrow R2 - R1.
Then i did R3\rightarrowR3-1.
so my new matrix was [(1,1,1), (0,0,-1), (0,-1,-1)].
