$2K(s) + 2H2O(l) → 2KOH(aq) + H2(g)$

Before including coefficients there are two hydrogens, one oxygen and one potassium in reactant side and there are three hydrogens, one oxygen and one potassium. Water and potassium gets coefficient two in reactant side and potassium hydroxide gets two in product side. Now in both sides the elements are balanced.
