PRACTICAL STEPS INVOLVED IN SOLVING MAXIMISATION PROBLEMS (WHERE ANY CONSTRAINT HAS "≥" OR "=" SIGN).
Step 1→
  1. Add Non-negative Slack Variables in case of constraints having "≤" sign as usual in case of Maximisation Problems.
  2. Deduct Surplus Variables (say S1, S2) and Artificial Variables (say A1, S1) in case of constraints having "≥" sign as in case of Minimisation Problems.
  3. Add Artificial Variables (say A1, S1) in case of constraints having "=" sign. However, the contribution of Artificial Variables will be deducted in the Objective Function.
Step 2→ Follow steps 2 to 14 (given on Page 3.1 & 3.2) as usual in case of Maximisation Problems to obtain the Solution to the given problem.
