Form into an algebraic equation?

If I have a question (for the purpose of this discussion) say:

"How many even numbers are there which are divisible by 7 but less than 50000?"

How do I write this as an algebraic linear (or polynomial) equation?

Nah, I only gave the question as an example for the concept I wanted to know more about. Basically, I wanted to know how to frame an equation for the phrase "X is divisible by Y."

Note that the numbers you are looking for are exactly the numbers that are divisible by $$14$$, because $$14 = 2 \times 7$$.

I don't actually get your question or the purpose of your question. But the number of such numbers are $\left \lfloor{ \frac{500000}{14} }\right \rfloor\$
