I'm not sure I understand. Can u plz help, sir?
We have 4x1+3x2=z1 and 2x1+4x2=z2. By putting x1+x2=1 i ultimately got 2z1+z2=10. also, if production takes place in both plants, 3<z1<4 and 2<z2<4. so v get the diagonal line. the end points correspond to the points at which all production takes place in only 1 plant. what next?
