Please Obi-sci-kenobi. You're my only hope. I know this

a solution:
[math] \begin{bmatrix} 0 \\ 0 \\ 0 \\ 1 \\ 0 \end{bmatrix} [/math]

2 1 1 0 0 -1
0 0 1 1 0 1
0 0 0 0 1 0

>>7800858
>2 1 1 0 0 0

row-1 looks incorrect, should be
2 1 2 1 0 0

>>7800883
Yeah you're right

But now what?

>how to solve matrices
Can we stop blindly throwing the word "solve" around anytime there's math involved?

At the bottom I referred to equations, implying that this is an augmented matrix

I am trying to solve a system of equations

>>7800858
The relevant matrix is 3x5, rank 3. You will have a 2 dimensional space of solutions. Find one solution p, and a basis for the kernel of the matrix k1,k2, the solutions will be p + c1 k1 + c2 k2.

Or something.

To find a particular solution, consider the first two rows, columns 2
and 3 (plus augmentation):

1 3 1
0 1 1

A solution is [-2,1]. So for the original, [0,-2,1,0,0] is a solution.

Now find the kernel.
