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)
