Thanks, I've the error in chapter 16.
But I don't get the equations mentioned in chapter 08, could you make a more specific description?

Thank you~

解法：另所有自由变量取0，则有
X1+2X3 = 0
2X3 = 0
解得X1 = -2 X3=3/2

The Prof. took b1=1,b2=5,b3=6 for example which subjects to b3-b2-b1 =0 condition. So if we set free varibales =0 , we should get X1+2X3 = 1;2X3=3，and solve this equations.

Sorry, my mistake.
Thanks a lot~
