Use workspace variable in equation solver

I have the equation x+y=25 and currently I have y as a predfined variable=5. so the equation becomes x+5=25. However I would like to change y from my script and the equation to automatically change based on my y value rather than me modifying my equations each time to edit the y value.
I currently do it this way:
y=5;
syms x
eqn = x+5=25;
S = solve(eqn,x);

If you don't want to use a function to wrap the input, you can use an anonymous function instead.
y=5;
syms x
eqn =@(y) x+y==25;
S = solve(eqn(y),x)
