Are you familiar with Matrices and RREF? You can use Matrices to simplify this process a lot.
ok these are the equations...
8k - 5n = 8r
3u + 2o = 189
5d + 2c = 6m
5L + 4m = 23b
3r - m = 3u
3k - 4i = 2i
3n - 3o = c
o - c = 4d
8i + 9r = 9n
10m + 7d = 3n
4d + 4e = 6b
4y - 6u = 2m
6b + 3c = 14m
now i need to find out what each variable really is...any help?
Alright. Well first of all, if your teacher won't let you use any method possible than this is pointless. If you can, this involves making a Matrix that has N rows, where N is the number of variables and N+1 columns. Do you have a calculator that can perform Matrix operations?
