Hi all,

I am struggling with a Problem at the momment,

ax + by + cz = e

I have a data set of "e" to "x" ,"y","z", and would like to get a possible range of the constants "a","b","c" .

data set eg.

e - x - y - z

6 - 11 - 1713 - 54

4 - 11 - 1123 - 25

2 - 9 - 1546 - 64

1 - 10- 789 - 87

the idea is to have an equation where x,y,z are entered and e is aquired.

Any help will be much appriciated.

Thanks
