How to fix error in fsolve

I want to solve following function

function F = root2d(x)
F(1) = X(1) - exp(13.5-(2700/(x(3)-55)));
F(2) = x(2) - exp(14-(3050/(x(3)-57)));
F(3) = 0.4*x(1) - 140*x(2);
F(4) = 0.6*x(2) - 140*x(5);
F(5) = x(4) + x(5)-1;

And I am getting following error

Error in root2d (line 3)
F(1) = X(1) - exp(13.5-(2700/(x(3)-55)));

Error in fsolve (line 258)
            fuser = feval(funfcn{3},x,varargin{:});

Is it just a case of changing

F(1) = X(1) - exp(13.5-(2700/(x(3)-55)));

to

F(1) = x(1) - exp(13.5-(2700/(x(3)-55)));

Thank you but Even after correcting the case,

and using following function

fun = @root2d;

x0 = [0,0];

x = fsolve(fun,x0)

I am getting following error

Index exceeds the number of array elements (2).

Error in root2d (line 2)

F(1) = x(1) - exp(13.5-(2700/(x(3)-55)));

Error in fsolve (line 258)

fuser = feval(funfcn{3},x,varargin{:});

Caused by:

Failure in initial objective function evaluation. FSOLVE cannot continue.

Your F expressions contain x(1) to x(5), but you only pass two values, [0, 0] to the function.
