Then, looking at the number of oxygen atoms, we can say that 6x + y = 2y. Substituting y for 6x we can then look at the chlorines on both sides and say that 2x + 2y = 2x + z (where z = number of moles of HCl) So we get 12x = z. So we have proof that the coefficients are, x, 6x, x, 6x, 12x.

When solving a simple equation, think of the equation as a balance, with the equals sign (=) being the fulcrum or center. Thus, if you do something to one side of the equation, you must do the same thing to the other side. Doing the same thing to both sides of the equation (say, adding 3 to each side) keeps the equation balanced.
