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)
