comment Solving system of equation with many variables and parameters
Thanks for your input. In deed MATLAB gave me monstreous formulas. You gave me a hope I could get better result. I just need to find more time and paper to do the calculation.

comment Prove existance of linear mapping
may I just say, that it is a linear mapping, that transfers bases $b_{s+1}-b_n$ to zero vector? (if $\dim(K) = s$)
