The process of photosynthesis says
6C02 + 12H2O ---- C6 H12 O6 + 6O2 + 6H2O (as given in the book)
it is a balanced equation..
cant we rewrite it such that

6C02 + 7H2O ---- C6 H12 O6 + 6O2 + H2O
consider the above equation. It is also balanced. Can we write photosynthesis in that way ?

Solution

No.
We cannot balance photosynthesis in that way because the equation given in the book is the resultant of two or more equation.
The reduction of six CO2 in photosynthesis requires 24 e- , producing one C6H12O6 and six H2O. Twelve H2O must be oxidized through photolysis to generate these 24 e-. This produces six O2.

To reduce the carbon in CO2, four e- are required. One oxygen atom is separated from the carbon, forming one H2O by gaining one e- and two H+. The carbon atom is reduced, gaining one e- and one H+, and the oxygen remaining with the carbon gains one e- and one H+..
