I need a matlab code that will solve this equation: x = 0.05t + 8.65ln(1 + (x/8.65)) when "t" is given?

What have you done so far? What specific problems are you having with your code? What methods of solving this are you allowed to use?

We can use any method of solving but the issue is that I really have no idea how to use matlab but this is the tool we were told to use so that we can use it later in the class

As James Tursa said, the question lacks of information. If it is a homework, I guess you should implement your own algorithm to solve the problem.
Considering matlab built-in functions, it is worth givinge a chance to fsolve
doc fsolve
and play with your function. For example
t = 1; % given value
% your function in the form f(x) = 0
f = @(x)0.05*t + 8.65*log(1 + (x/8.65))-x;
% starting point (maybe you have a better initial guess)
x0 = 1;
% fsolve
xsol = fsolve(f,x0)
Note that fsolve have many inputs and tolerances to play with.
