The problem statement clearly states to use mldivide (\)
How can the leading solution be cos(theta)+sin(theta)*[-1;1]

My code is working perfectly on my desktop Matlab version, but here it's not accepting and displaying as incorrect..anyone help me out!

The syms function is in a toolbox—Cody does not currently support any toolbox functions.

It is tricky problem.
A=[cos(theta) sin(theta); -sin(theta) cos(theta)]; % coefficients of X1 and X2
b=[1;1] % It is a column vector

What is this? I don't even understand the question?
The answer is:
A=[cos(theta) sin(theta); -sin(theta) cos(theta)]; % coefficients of X1 and X2
b=[1;1] % It is a column vector

function x = solve_lin(theta)
A=[cos(theta) sin(theta); -sin(theta) cos(theta)];
b=[1; 1];
x=linsolve(A,b);
end
