Can we apply simplex method if one or more equation are equal to zero. tell me full criteria my question example is as follows:
Maximize: $z=135x+50y$, subject to:
$$\begin{align} 2x+\frac{1}{2}y&=32 \\ 4x-y&=0 \\ 4x+y&=64 \\ \end{align}$$
Tell me its full criteria to solve it I want to confirm it now .
