Really, really struggling with this question.
I've tried using a few examples but I cant seem to get narrow down 3 terms to just 1.
I always end up with 2 letters/terms remaining.
The 3 equations I have are:
7i + 8ii + 7iii = 2 (Equation 1)
6i + 7ii + 5iii = 8 (Equation 2)
6i + 9ii + 6iii = 2 (Equation 3)
So I need to work out the values for i, ii and iii.
I tried using the 3 step procedure as described in a text book I have. But it doesn't seem to work.
I hope someone can help.
