2x- y+ z=1
x+2y+3z=8
3x+ y-4z=1
There are many ways to solve this.
Since you didn't state a method, we're
not just going to guess one particular
way. If you want to see it solved,
specify which method you are studying,
tell me in the thank-you note form below,
and I'll get back to you.
The solution is
x=1, y=2, z=1
