Update: answer mod-deleted. This is not a VLQ, but it is an NAA. Please see my answer for explanations.
In LP-problem simplex with 3 variables, the question asker asks for "simplex calculations". Anyone who knows some introductory linear-programming will understand that this stands for "simplex algorithm", which is an algorithm iterating through the extreme points of the (convex) set of possible solutions. Obviously, he/she is expecting a solution with a simplex tableau.
The main goal of such kind of exercises is to get students know the simplex algorithm through practising it (on paper). This is the basics just like warm-up exercises for further topics in LP such as sensitivity analysis. To assess student's understanding of the simplex algorithm in a two-hour exam, teachers may set up an "easy" problem like this and ask students to solve it using the algorithm, so that students can verify their final results found by the algorithm through comparing them with those found by directly solving the system.
The answer in this question shows no simplex iteration, so it's
VLQ and NAA. I used the former flag, so that it entered into LQ review. Unluckily, only one reviewer has noticed this. The other reviewers have never created a post in linear-programming. Despite my comment at the bottom, they have voted "Looks OK". As a result, I've used the second flag. Please delete this answer.
