MATLAB: The solve function in matlab isn’t working.

Question

I've inserted the following codes:

clear,clc

syms x y

A=solve('x+y=1','x-y=0');

just with the same shown order, however, when i run it gives me nothing except some errors.

How can I solve the problem?

PS: the errors:

Error using solve>getEqns (line 418)

List of equations must not be empty.

Error in solve (line 226)

[eqns,vars,options] = getEqns(varargin{:});

Error in code2 (line 3)

A=solve('x+y=1','x-y=0');

Answer 1

Rather than specifying the inputs to solve as char vectors, you should specify them as symbolic equations.

syms x y
A = solve(x+y == 1, x-y == 0)
