How can I change a variable in a equation when use "solve"?

Dear all,

A question about using the solve function. My code is as follows,

syms a x y
s = solve('x*exp(x)=y, y=a-x','x,y')
s = [s.x s.y]

It works when I use a number such as "2" instead of "a" in the equation 'y=a-x'. But when I include the variable in the equation, it doesn't go. Since I want to change the "a" value outside the "solve" function, how can I do this?

The matlab version is R2010a.

Many thanks!

Jing
