Please execute the "ver" command. You should have something like
Symbolic Math Toolbox Version 6.1 (R2014b)
as part of the output. If not, that is the answer, you do not have the Symbolic Math Toolbox. If you do have, let's see what
which syms -all
returns

The Symbolic Mathematics Toolbox is an optional product from Mathworks that you would purchase a license for.
Note: Symbolic Mathematics Toolbox is one of the products that is included in the Student Suite bundle.

I am having Symbolic Math Toolbox with 2017a version. Still unable to use syms.
It gives me an error:
Error using mupadmex
Error in MuPAD command:
Error in sym>cell2ref (line 1308)
S = mupadmex(y);
Error in sym>tomupad (line 1246)
S = cell2ref(numeric2cellstr(x));
Error in sym (line 199)
S.s = tomupad(x);
Error in syms (line 192)
toDefine = sym(zeros(1, 0));
Error in switched_mode (line 1)
syms x y
How do I resolve this?

You will probably need to reinstall Symbolic Math Toolbox
