Compute the top border of an integral

Hello,

my function looks like:

Now I like to compute T, I know everything else except the function f(x). (Sadly, f(x) is a "closed" function. It's just possible to give an input and get an output, but not more. I don't know how f(x) looks like.)

My approach was: >> fun = @(x)f(x); >> solve(integral(fun,A,T)+integral(fun,B,T)==C,T);

But it didn't work this way. Thanks for better ideas!

The INTEGRAL and FZERO functions will be of use to you.
