"First, a feasible solution must be found. Since the right-hand side is negative, we cannot simply choose $x_i=0$, since this would contradict $w_1\geq 0$. Instead, it may be seen that letting $x_1=x_3=w_1=0$ and thus $x_2=2$ and $w_2=3$ is a feasible solution to the problem. " - Simplex negative right hand side
