Answer:
(x, y, z) = (x, x+2, 3x+1)
Step-by-step explanation:
We can add twice the second equation to the first to get ...
[eq4] -3x +0y +z = 1
Adding the first and second equations gives ...
[eq5] -x +y +0z = 2
Solving [eq4] for z gives ...
z = 3x +1
Solving [eq5] for y gives ...
y = x +2
Then the solution triple is (x, y, z) = (x, x+2, 3x+1).
