code runs in Matlab but isn't accepted in Matlab grader. Please fix the code(Matlab grader is VERY specific with requirements)

Create the symbolic expression shown then use the subs command to evaluate the expression for x=4. Save the final value as y value with the class 'double' y=x215x42x y=x215x42x Script * Define the symbolic variable x 5y ys x \% Define the symbolic expression y y=(5x4+2x)/(x21) \% substitute x with the value 4 \[ y \text { _value }=\operatorname{double}(\operatorname{subs}(y, x, 4)) ; \] 7o Display the result disp([The value of y for x=4 is: " num2str (y_value)]); evious Assessment: 1 of 3 Tests Passed Check expression y Variable y has an incorrect value. Make sure you defined x as a symbolic variable before creating the expression for y. Re-check the expressinn for n Check y_value Variable y_value has an incorrect value Verify that you named the variable eorrectly and used the correct substitution Check for subs and double commands Output The value of y for x=4 is: 85.8667
