NH3 + O2 -> NO + H2O

On your left are your reactants; NH3 + O2
On your right are your products; NO + H2O

Make a T - chart, writing reactants and products

On your left side write your products down;

N: 1
H: 3
O:2

On your right side write your products down;

N: 1
O: 2 (one on NO and the other on H2O
H: 2

Then you compare both sides to make them both equivalent or equal.

On your left your reactants should look like;

N: 1 x 2 = 2
H: 3 x 2 = 6


On your rights your products should look like;

N: 1 x 2 = 2
H: 2 x 3 = 6

Notice how I did not write O2. That’s because on your left, your reactants won’t match.

It will look like this;

On your left;

O: 2 x 5/1 = 10/2 = 5/2

On your right;

O: 2 + 3 = 5

You can’t have a fraction in your balances equation so the next thing you’ll do is multiply everything by 2.

2 •(2NH3 + 5/2O2 -> 2NO + 3H2O)

Finally your answer will be;

4NH3 + 5O2 -> 4NO + 6H2O

Hope this helps!
