2. Tableau Padded with slack variables:
----------------------------------------------------------------------
col:   b[i]    x1,    x2,    x3,    x4,    x5,    x6,    x7,    x8,

Most negative column in row[0] is col 4 = -4.
Entering variable x4 to be made basic, so pivot_col=4.
Ratios A[row_i,0]/A[row_i,4] = [1.#J, 1.#J, 1.#J, -8.00, ].
Found pivot A[1,4], min positive ratio=1.#INF in row=1.
Leaving variable x1, so pivot_row=1
