So, let's say that I have two functions which depends on two variables, say x and y and the function also has two real parameters a and b.
Then you also have a term Q which is a linear combination of the previous functions, and this expression still depends on x and y, with the parameters a and b.
Now you have a final term which is some constant plus the term Q, and this will depend only on x, with a fixed known y.
How would you express such a thing in mathema
