Balancing Equations (Year 10) (1 Viewer)

Hey guys.
I need some help in balancing Chemical Equations.

e.g.
C2H6 + O2 -> H2O + CO2
aC2H6 + bO2 -> cH2O + dCO2

b=7/2 a
c=3a
d=2a

aC2H6 + 7/2aO2 -> 3aH2O + 2aCO2
Answer: 2C2H6 + 7O2 -> 6H2O + 4CO2

The answer is correct, however is there another way to solve this? Which method would be most reliable?

Thank you in advance.

You should just do it intuitively, deal with the carbons followed by the hydrogens, always do oxygen last.

Personally, I don't use the a, b c d method I just do trial and error, I find it works best.
