I don't see any reason to split equality equations into two inequalities. One can directly add an artificial variable in the equality constraint 3 x 1 + 2 x 2 = 18 and proceed with Big M or Two Phase method to obtain the solution.

WebbThe simplex method is a systematic procedure for testing the vertices as possible solutions. Some simple optimization problems can be solved by drawing the constraints … The tableau form used above to describe the algorithm lends itself to an immediate implementation in which the tableau is maintained as a rectangular (m + 1)-by-(m + n + 1) array. It is straightforward to avoid storing the m explicit columns of the identity matrix that will occur within the tableau by virtue of B being a subset of the columns of [A, I]. This implementation is referred to as the "standard simplex algorithm". The storage and computation overhead is such t…
