**(1) 2x - y = 2**

**-x + 3y + 2z = 1**

**x + 2y + 2z = -1**

I created an augmented matrix from this and row reduced to the point where I have:

|1 -3 -2 | -1|

|0 1 4/5 | 0|

|0 5 4 | 0|

Not sure if I did incorrect calculations or what, but I have no idea where to go from here (provided I did the correct calculations up to this point). Please help me out!

**(2) w + 2x - y - 2z = -1**

**x - y = -1**

**-w + 2x + z = -1**

Here I also row reduced but only went through one round of reducing before coming to the conclusion that there's no solution...Yes or no?

Please, please help -- I really am quite lost with both of these!
