Newbie Joined: Nov 2016 From: England Posts: 2 Thanks: 0  Gaussian Elimination I've attempted this problem and got that it has infinite solutions. In the first instance, are the row reductions I've done valid and correct? And if so, how do I get solutions from the last bit? Any assistance appreciated. Thank you.

Your operations are valid, but your first annotation is not quite correct. You can deduce that y and z can have any values that satisfy 2y + 3z = 2, and the value of x is then given by x = 3  y  z.
