Correction: 02:01 – The constraint 2 has a sign error. Instead of 2 x2+s2 less than equal to it should be equal to.
Big M method! This method is used in Linear Programming, when we have to solve problems involving '=' or greater that equal to constraints. We have additionally a variable M to take care in each row operation involving objective functions. It is easy to get puzzled with it as it has no values and ends up in fractions!!! This is a novel method to solve it in the calculator. It makes the calculation error free and a lot faster. Watch to learn. Ace in your exams.
