% Testing equation is
% function = 0.08 - 0.0314*(T-298) - 5.346*(10^-11)*((T^4) - (298^4) = 0

% 1. we define the function,
% 2. Insert T value to the function, here we insert T values from 200 to
%    400 using while loop. 
% 3. One T value will give a value of function(eq). We check that value is
%    close to the zero ( approximately smaller than 0.01, this value cc=an
%    be changed later)
% 4. When value of function becomes smaller than 0.01 loop breaks, and that T
%    value is taken as the answer.

T = 200;


while T<400
eq = 0.08 - 0.0314*(T-298) - 5.346*(10^-11)*((T^4) - (298^4));
 
if(eq<0.01)   
%use round function if you want to get the answer into integer    
answer_T = round(T);
fprintf('%d\n',answer_T);
break;  
end

%increse the T value by 0.1 each time
T = T + 0.1;

end
