Symbol x

Its job in the formula

x is part of the quantity the equation computes from the expression on the right.

Where the article explains it

Writing x for invested Attack EVs and y for invested Speed EVs and relaxing the two internal floors to their continuous approximation for tractability, Garchomp’s Jolly-natured sweep index becomes f(x,y) = (296+x/4)(264+0.275y) , and maximizing it subject to a shared budget x+y=B through a Lagrangian $\mathcal{L}(x,y,\lambda)$ = (296+$\tfrac{x}{4}$)(264+0.275y) - $\lambda(x+y-B)$ produces first-order conditions $\tfrac{1}{4}$(264+0.275y) = $\lambda$ = 0.275\,(296+$\tfrac{x}{4}$) , which reduce, after clearing terms, to a single tangency condition independent of the budget size: y - x = 224 The unconstrained-by-caps answer, in other words, wants Garchomp’s invested Speed to run 224 points ahead of its invested Attack — a gap wider than the entire 252-point ceiling on either stat individually.

A variable is a named place for a value. Its letter is a local label: x can mean position in one formula and a data point in another.
