Write the basic solution for the simplex tableau determined by setting the nonbasic variables equal to 0.

x1 x2 x3 x4 x5 z

Or x1 = 0, x2 = 0, x3 = 0, x4 = 0, x5 = 4, z = 1

x1 = 0, x2 = 0, x3 = 3, x4 = 6, x5 = 0, z = 1

Or x1 = 3, x2 = 6, x3 = 3, x4 = 6, x5 = 0, z = 3

x1 = 3, x2 = 0, x3 = 0, x4 = 6, x5 = 0, z = 3
