The code was:
syms x
limit((5x-3)/x,x,inf)
And the problem was:
Error: File: Untitled2.m Row: 2 Column: 9
Should not be a MATLAB expression.

It works for me. Well, as long as I understand how to multiply in MATLAB.
syms x
limit((5*x-3)/x,x,inf)
ans =
5
If you ignore the rules of MATLAB syntax, then expect random garbage as a result. Note the use of 5*x, whereas 5x is syntactically invalid.
