**Linear Algebra - System of 2 Equations with 3 Variables--possible?**

## Homework Statement

Solve: x1-3x2+4x3=-4

3x1-7x2+7x3=-8

-4x1+6x2-x3=7

## The Attempt at a Solution

I was able to make it to:

1 -3 4 -4

0 -10 25 -11

0 0 0 0

So the third row goes away, and I am left with:

1 -3 4 -4

0 -10 25 -11

I am pretty sure that cannot be solved, or am I overlooking something? Thank you in advance!!
