Thank you so much sir for this good explanation but It is not mentioned anywhere that we can't solve maximisation problem through 2phase method. Infact in A.M. Natrajan book all minimization is first converted in maximization and the it is solved.

Since when do you subtract a slack variable? As far as I know you ADD a slack variable when the < sign appears and subtract a AXCESS (-e) when the > sign appears and add a artificial variable with that axcess variable. so it will look like this 2 x1 + 3 x2 + 1 x3 = 12 will be 2 x1 + 3 x2 + 1 x3 -e1 + a1 = 12
