I don't know which technique was developed in this unknown to me section,
which you do mention in your post.

Therefore, I recommend you to go to this (free of charge) online Internet solver
https://www.zweigmedia.com/RealWorld/simplex.html

Read the instructions; print there (or copy-paste) your input data in this format

Minimize C = x − 6y + z subject to
x − 2y + 3z <= 10
2x + y − 2z <= 15
2x + y + 3z <= 20
x >= 0, y >= 0, z >= 0  

The solver will give you the solution momentarily

     Optimal Solution: c = 0; x−6y = 0, z = 0

with all necessary explanations, step by step.

Solved.
