In my script it says the answer should be (x1, x2, x3, x4) = (0, 3a+4b, b, a). I did it 5 times, and I always get the same result. Can someone point me to the problem please? As for the i) one, I'm pretty sure I'm doing something wrong, however I just can't seem to find it. Any help welcome, please, I need it for my exam. Correct answer for i) is: (x1, x2, x3, x4, x5) = (3/10  a  b, a, 1/2  20b, 1/10  7b, 5b)

Your answer for (h) is equivalent to theirs (they used a, whereas you used S). For (i), see your other thread.
