Homework Equations
The Attempt at a Solution
Question 1
x4 = 1 + 4x5
but from there I am not sure where to go or if there is even a solution?
Question 2
I eventually got the matrix down to this:
Code:
1 2 -3 1 4 1
0 1 1 0 1 1
0 0 1 0 -1/3 -1/3
0 0 0 1 -1/3 4/3
but again I am not sure if that is enough? I don't understand how back substitution is possible.
Question 3
Similar to 3. I sort of got it to row-echelon, but am having trouble. Any help on the previous question should help here.
Thanks
