Combining symbolic differential equations

Hello,
I have the following two equations:
syms R C positive
syms u_e(t) u_a(t) i(t)
eq1 = u_e(t) == R * i(t) + u_a(t)
eq2 = i(t) == C * diff(u_a(t), t)
I want to use the expression i(t) of equation 2 in equation 1. Using solve does not help.
solve(eq2, i(t))
Could anyone give me a hint, how to do this?
Michael
