Hello Shimon. What error are you getting? Do you have the Symbolic Math Toolbox add-on?

Here's a thread you might find useful. :)

Once you have the Symbolic Math Toolbox add-on, you may solve the equation like this

syms x
eqn = x - 2 == 0;
solx = solve(eqn, x)

You'll find this link useful too.

Hope this helps. :)

Do you have Symbolic Math Toolbox?

Try the following:

syms x
fcn = x-2;
solve(fcn == 0)
