## Homework Statement

Find out if the following system of equation has solution. In case of having solutions, describe parametrically them all and give 2 of them explicitly.

2x-z=4

x-2y+2z=7

3x+2y=1

**2. The attempt at a solution**

I don't see nowhere in my notes what they want by "describe parametrically".

Anyway I've solved the system and it has only one solution : x=2, y=-5/2 and z=0.

As I just typed them, it is the explicit solution... I don't see how I could give 2 of them if there is only 1 solution. And much less parametrically.

Do you know what they mean?
