1. The problem statement, all variables and given/known data 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?
