    how to merge system of recurrence equations

    Hi all,
    I have two recurrence equations and an algebric one that I would like to merge:
    x1(n+1)=x1(n)+t*u(n)-t*x2(n)
    x2(n+1)=x2(n)+t*y(n)/q(n)+t*d(n)/q(n)
    y(n)=p1(n)*x1(n)+p2(n) *u(n)-p2(n)*x2(n)

    I'd like to wright a single equation without x1 and x2, how to do that?
    thanks

    Hi,
    I found this method to reduce system of recurrence equation: System of recurrence relations
    However, I did'nt found a way to apply this method to my problem as my recurrence equation couldn't be written in a linear equation relating x(n) and x(n-1), in addition my las equation is not recurrent.
    Can't we use a similar way to reduce my system of equations?
    What would be the analogue of caracteristic polynomial for my problem?
    thanks
