Math problem

I could be wrong, but if you have 5 missing variables, do you not need 5 working solutions to get each value.

Yes. I have to get x1,x2,x3,x4,x5 from x6,x7,x8 results.

Thank You.

Or to use some other results to get x1, x2, x3, x4, x5.

Thank You.

I think you misunderstand me.
What I meant to say is, if my old maths is correct, is that you cannot get values for x1, x2, x3, x4, x5 if you only have 3 solutions x6, x7, x8.
You need at least 2 more calculations to make x9 and x10 before you can get x1, x2, x3, x4, x5

Please mikelittlewood, if You can make more calculations x9 and x10, because I don't know how to perform correctly results x6, x7 and x8 to get x1, x2, x3, x4 and x5 values.

Thank You.

ghjlk,
this is the list of possible solutions I get when I run the above code:

x1=33, x2=2, x3=17, x4=25, x5=66
