Enter symbolic multivariable equalities in matlab

Hi everybody,
I'm trying to implement a symbolic equality but instead of define a variable, I need to define a group of variables. My equation is like this : theta^2*ue^b/nu=a*int(ue^(b-1),x0,x) The problem is that matlab does not allow me to have multiple variables on the left hand side of the = sign. Ofcourse I can rewrite it to a theta = ... but I need to represent my answer in the form of theta^2*ue^b/nu. I tried defining an equation like this eq1= ' theta^2*ue^b/nu=a*int(ue^(b-1),x0,x)' but then it just defines it as a string, and I lose arithmetic possibilities (such as a substitution which i need to perform)
I know Matlab 2012b has the == function for the symbolic toolbox, but I'm running 2011a. Does anyone know a way to this?
Thanks in advance for your time.
Roy

syms theta nu a ue b x0 x
equation=theta^2*ue^b/nu-a*int(ue^(b-1),x0,x)

this équation is by default equal to zero
solve(equation) is the same then solve(equation==0)
