I like Serena said:It shouldn't be feasible since it corresponds to the intersection of thered line(non-basic variable $P_4$) and thegreen line(non-basic variable $P_5$).

When $a > \frac 32$ that intersection should have either $x_2 < 0$ or $x_1 < 0$.

So have I done something wrong at the calculations? (Thinking)Which $a$ did you pick to draw the third inequality?
