problem in equation solving in octave

[shm]

Hi,

I am solving a set of differential equations by using lsode solver. But the
problem is that if i use value of one equation in another, it not only
changes the value of that equation but also in itself accordingly.
For example:

xdot (1)= x(1)*a + b*(1-exp(-x(2));
xdot(2)= a*x(2);
 
The equation xdot(2) keep on changing according to equation 1 even if i set
it equal to zero.
What could be the problem?
