The equation is

H2O - > H2 + O2

Now, it should be balanced. In order to balance it, the amount of atoms on the both sides must be the same. There is one O atoms on the left side an two on the right. In order to balance the equation, write a coefficient 2 in front of H2O

2 H2O - > H2 + O2

But now there are four H atoms on the left and two on the right. Thus, you should write a 2 in front of the H2, too.

2 H2O - > 2 H2 + O2
